desktop: fix AppImage patch step using absolute paths

The patch step cd's to a temp directory for extraction, so the
AppImage path must be absolute (via $GITHUB_WORKSPACE).

+# Panel Interface Refactor Plan
+
+**Goal:** Replace the hardcoded panel switch statements with a registry-based panel interface. This is a pure refactor — all product surfaces stay identical. The motivation is to prepare for split panes (VSCode-style), where each split independently renders panels.
+
+## The Problem
+
+The workspace screen (`packages/app/src/screens/workspace/workspace-screen.tsx`, ~2084 lines) has a `renderContent()` function (line 1437) that switches on `target.kind` to render each panel type with bespoke props. The same pattern repeats in:
+
+- `workspace-tab-model.ts` — switches on `target.kind` to build tab descriptors (labels, subtitles, status)
+- `workspace-tab-presentation.tsx` — switches on kind for icons and status indicators
+
+Every new panel type requires editing 3+ files. This must become a registry where panels self-register.
+
+## Target Architecture
+
+### 1. PanelRegistration Interface
+
+```typescript
+// panels/panel-registry.ts
+
+interface PanelDescriptor {
+  label: string;
+  subtitle: string;
+  titleState: "ready" | "loading";
+  icon: React.ComponentType<{ size: number; color: string }>;
+  statusBucket: SidebarStateBucket | null;
+}
+
+interface PanelRegistration<K extends WorkspaceTabTarget["kind"] = WorkspaceTabTarget["kind"]> {
+  kind: K;
+  component: React.ComponentType;
+  useDescriptor(
+    target: Extract<WorkspaceTabTarget, { kind: K }>,
+    context: { serverId: string; workspaceId: string },
+  ): PanelDescriptor;
+  confirmClose?(
+    target: Extract<WorkspaceTabTarget, { kind: K }>,
+    context: { serverId: string; workspaceId: string },
+  ): Promise<boolean>;
+}
+```
+
+### 2. Panel Registry
+
+```typescript
+const panelRegistry = new Map<string, PanelRegistration>();
+
+function registerPanel(registration: PanelRegistration): void {
+  panelRegistry.set(registration.kind, registration);
+}
+
+function getPanelRegistration(kind: string): PanelRegistration | undefined {
+  return panelRegistry.get(kind);
+}
+```
+
+### 3. PaneContext
+
+Every panel gets workspace-level context via `usePaneContext()`. No prop drilling of serverId/workspaceId through panel-specific props.
+
+```typescript
+interface PaneContextValue {
+  serverId: string;
+  workspaceId: string;
+  tabId: string;
+  target: WorkspaceTabTarget;
+  openTab(target: WorkspaceTabTarget): void;
+  closeCurrentTab(): void;
+  retargetCurrentTab(target: WorkspaceTabTarget): void;
+  openFileInWorkspace(filePath: string): void;
+}
+```
+
+### 4. WorkspaceTabTarget stays unchanged
+
+```typescript
+type WorkspaceTabTarget =
+  | { kind: "draft"; draftId: string }
+  | { kind: "agent"; agentId: string }
+  | { kind: "terminal"; terminalId: string }
+  | { kind: "file"; path: string };
+```
+
+No store migration needed. `serverId` and `workspaceId` come from the pane context, not the target.
+
+## Panel Implementations
+
+Each panel type gets its own file that exports a `PanelRegistration`. Panels use `usePaneContext()` for workspace-level context and read their own data from stores directly.
+
+### Agent Panel Example
+
+```typescript
+// panels/agent-panel.ts
+
+function useAgentPanelDescriptor(
+  target: { kind: "agent"; agentId: string },
+  context: { serverId: string },
+): PanelDescriptor {
+  const agent = useSessionStore(
+    (s) => s.agentsByServer.get(context.serverId)?.get(target.agentId) ?? null,
+  );
+  const provider = agent?.provider ?? "codex";
+  const label = resolveAgentLabel(agent?.title);
+  return {
+    label: label ?? "",
+    subtitle: `${formatProviderLabel(provider)} agent`,
+    titleState: label ? "ready" : "loading",
+    icon: agentIconForProvider(provider),
+    statusBucket: agent ? deriveAgentStatusBucket(agent) : null,
+  };
+}
+
+function AgentPanel() {
+  const { serverId, target, openFileInWorkspace } = usePaneContext();
+  invariant(target.kind === "agent", "AgentPanel requires agent target");
+  return (
+    <AgentReadyScreen
+      serverId={serverId}
+      agentId={target.agentId}
+      showExplorerSidebar={false}
+      wrapWithExplorerSidebarProvider={false}
+      onOpenWorkspaceFile={openFileInWorkspace}
+    />
+  );
+}
+
+export const agentPanelRegistration: PanelRegistration<"agent"> = {
+  kind: "agent",
+  component: AgentPanel,
+  useDescriptor: useAgentPanelDescriptor,
+  async confirmClose(target, context) {
+    const agent = useSessionStore.getState().agentsByServer.get(context.serverId)?.get(target.agentId);
+    if (agent?.status === "running") {
+      return confirmDialog({ title: "Agent is still running. Close anyway?" });
+    }
+    return true;
+  },
+};
+```
+
+### Terminal Panel Example
+
+```typescript
+function useTerminalPanelDescriptor(
+  target: { kind: "terminal"; terminalId: string },
+  _context: { serverId: string; workspaceId: string },
+): PanelDescriptor {
+  // read terminal data from appropriate store
+  return {
+    label: "Terminal",
+    subtitle: "Terminal",
+    titleState: "ready",
+    icon: TerminalIcon,
+    statusBucket: null,
+  };
+}
+
+function TerminalPanel() {
+  const { serverId, workspaceId, target, openTab } = usePaneContext();
+  invariant(target.kind === "terminal", "TerminalPanel requires terminal target");
+  return (
+    <TerminalPane
+      serverId={serverId}
+      cwd={workspaceId}
+      selectedTerminalId={target.terminalId}
+      onSelectedTerminalIdChange={(terminalId) => {
+        if (terminalId) {
+          openTab({ kind: "terminal", terminalId });
+        }
+      }}
+      hideHeader
+      manageTerminalDirectorySubscription={false}
+    />
+  );
+}
+```
+
+### Draft Panel Example
+
+```typescript
+function useDraftPanelDescriptor(
+  _target: { kind: "draft"; draftId: string },
+  _context: { serverId: string; workspaceId: string },
+): PanelDescriptor {
+  return {
+    label: "New Agent",
+    subtitle: "New Agent",
+    titleState: "ready",
+    icon: PencilIcon,
+    statusBucket: null,
+  };
+}
+
+function DraftPanel() {
+  const { serverId, workspaceId, tabId, target, openFileInWorkspace, retargetCurrentTab } = usePaneContext();
+  invariant(target.kind === "draft", "DraftPanel requires draft target");
+  return (
+    <WorkspaceDraftAgentTab
+      serverId={serverId}
+      workspaceId={workspaceId}
+      tabId={tabId}
+      draftId={target.draftId}
+      onOpenWorkspaceFile={openFileInWorkspace}
+      onCreated={(agentSnapshot) => {
+        retargetCurrentTab({ kind: "agent", agentId: agentSnapshot.id });
+      }}
+    />
+  );
+}
+```
+
+### File Panel Example
+
+```typescript
+function useFilePanelDescriptor(
+  target: { kind: "file"; path: string },
+  _context: { serverId: string; workspaceId: string },
+): PanelDescriptor {
+  const fileName = target.path.split("/").filter(Boolean).pop() ?? target.path;
+  return {
+    label: fileName,
+    subtitle: target.path,
+    titleState: "ready",
+    icon: FileTextIcon,
+    statusBucket: null,
+  };
+}
+
+function FilePanel() {
+  const { serverId, workspaceId, target } = usePaneContext();
+  invariant(target.kind === "file", "FilePanel requires file target");
+  return (
+    <FilePane
+      serverId={serverId}
+      workspaceRoot={workspaceId}
+      filePath={target.path}
+    />
+  );
+}
+```
+
+## How the Tab Bar Uses It
+
+Each tab chip calls the panel's `useDescriptor` hook:
+
+```typescript
+function TabChip({ tabId, target, serverId, workspaceId }: {
+  tabId: string;
+  target: WorkspaceTabTarget;
+  serverId: string;
+  workspaceId: string;
+}) {
+  const registration = getPanelRegistration(target.kind);
+  invariant(registration, `No panel registration for kind: ${target.kind}`);
+  const descriptor = registration.useDescriptor(target, { serverId, workspaceId });
+  return (
+    <TabChipChrome
+      tabId={tabId}
+      label={descriptor.label}
+      subtitle={descriptor.subtitle}
+      titleState={descriptor.titleState}
+      icon={<descriptor.icon size={16} color={theme.colors.foregroundMuted} />}
+      statusBucket={descriptor.statusBucket}
+    />
+  );
+}
+```
+
+## How the Workspace Screen Renders Content
+
+Replaces the entire `renderContent()` switch:
+
+```typescript
+function PaneContent({ tabId, target, serverId, workspaceId }: {
+  tabId: string;
+  target: WorkspaceTabTarget;
+  serverId: string;
+  workspaceId: string;
+}) {
+  const registration = getPanelRegistration(target.kind);
+  if (!registration) return null;
+  const Component = registration.component;
+  return (
+    <PaneProvider value={{ serverId, workspaceId, tabId, target, ...actions }}>
+      <Component />
+    </PaneProvider>
+  );
+}
+```
+
+## Implementation Steps
+
+### Step 1: Create panel registry infrastructure
+
+Create the following new files:
+
+- `packages/app/src/panels/panel-registry.ts` — `PanelRegistration`, `PanelDescriptor` types, registry map, `registerPanel()`, `getPanelRegistration()`
+- `packages/app/src/panels/pane-context.ts` — `PaneContextValue` type, React context, `PaneProvider`, `usePaneContext()` hook
+
+### Step 2: Create panel registration files
+
+Move panel-specific logic out of workspace-screen, workspace-tab-model, and workspace-tab-presentation into self-contained panel modules:
+
+- `packages/app/src/panels/agent-panel.ts` — agent component wrapper + `useDescriptor` + `confirmClose`
+- `packages/app/src/panels/draft-panel.ts` — draft component wrapper + `useDescriptor`
+- `packages/app/src/panels/terminal-panel.ts` — terminal component wrapper + `useDescriptor`
+- `packages/app/src/panels/file-panel.ts` — file component wrapper + `useDescriptor`
+- `packages/app/src/panels/register-panels.ts` — imports all panels, calls `registerPanel()` for each
+
+### Step 3: Refactor workspace-tab-model.ts
+
+Replace the per-kind descriptor derivation in `deriveWorkspaceTabModel()` with calls to `getPanelRegistration(target.kind).useDescriptor(...)`.
+
+Note: `deriveWorkspaceTabModel` is a pure function, not a hook. The `useDescriptor` hooks are called from React components (the tab bar). The model derivation may need to be restructured — the tab bar calls `useDescriptor` per tab, and the model just handles ordering and active-tab resolution.
+
+### Step 4: Refactor workspace-screen.tsx renderContent()
+
+Replace the `renderContent()` switch with `<PaneContent>` that uses the registry. Wire up the `PaneProvider` with the action callbacks that currently live as inline functions in the workspace screen.
+
+### Step 5: Refactor workspace-tab-presentation.tsx
+
+Move icon components and status derivation into each panel's registration. The shared `WorkspaceTabIcon` component becomes a thin wrapper that calls `registration.useDescriptor()` and renders the icon from the descriptor.
+
+### Step 6: Verify
+
+- `npm run typecheck` must pass
+- All existing tab behavior must work identically: open, close, reorder, retarget, keyboard shortcuts, context menus
+- Mobile tab switcher must work unchanged
+- No visual regressions in tab bar, icons, status indicators
+
+## Constraints
+
+- **Pure refactor** — zero user-visible behavior changes
+- **No new features** — no splits, no new panel types, no new keyboard shortcuts
+- **WorkspaceTabTarget stays unchanged** — no store migration
+- **workspace-tabs-store.ts stays unchanged** — the store is not part of this refactor
+- **Do not create index.ts barrel files** — project convention
+- **Use `invariant` from `tiny-invariant`** for asserting panel target kinds
+- **Use `function` declarations** — project convention (no arrow function components)
+- **Use `interface` over `type` where possible** — project convention
+- **Run `npm run typecheck` after every change** — project rule

+**NEVER bump the version to fix a build problem.** New versions are reserved for meaningful product changes (features, fixes, improvements). Build/CI failures are fixed on the current version.
+
+To retry a failed workflow for an existing tag:

+   ```
+2. **Platform-specific retry tags** (desktop only) — push a tag like `desktop-macos-v0.1.28` to rebuild just that platform against the release tag's code
+
+If the fix requires a code change (e.g. a broken build script), commit the fix to `main` and use `workflow_dispatch` pointing at the existing tag — the workflow checks out the tag ref, but for build-tooling fixes you may need to point it at `main` or cherry-pick the fix onto the tag.

+# Split Panes Plan
+
+**Goal:** VSCode-style split panes for the workspace screen. Users can drag tabs to edges to create horizontal/vertical splits, resize splits, and navigate between panes with keyboard shortcuts. Desktop/web only — mobile uses the same store but never creates splits (single pane).
+
+## Data Model
+
+### Core Types
+
+```typescript
+interface SplitPane {
+  id: string;
+  tabIds: string[];
+  focusedTabId: string | null;
+}
+
+interface SplitGroup {
+  id: string;
+  direction: "horizontal" | "vertical";
+  children: SplitNode[];
+  sizes: number[];  // proportional, sum to 1, same length as children
+}
+
+type SplitNode =
+  | { kind: "pane"; pane: SplitPane }
+  | { kind: "group"; group: SplitGroup };
+
+interface WorkspaceLayout {
+  root: SplitNode;
+  focusedPaneId: string;
+}
+```
+
+### Design Decisions
+
+- **Single store replaces the flat tab store.** The layout store owns tabs, tab order (per pane), and focused tab (per pane). No separate flat tab store.
+- **Mobile is just a single-pane tree.** Same store, same code paths. Mobile never calls split operations, so the tree never grows beyond one pane.
+- **Focused pane concept.** Common operations (`openTab`, `closeTab`, `focusTab`) route to the focused pane automatically. No `paneId` parameter needed for everyday use.
+- **`PaneContext` doesn't need `paneId`.** Split-specific operations (drag-drop, resize) are wired directly in split UI components that know their pane ID from tree rendering.
+- **Max depth: 4 levels.**
+- **Proportional sizes** that sum to 1. Minimum proportion per child: 0.1 (10%).
+
+### Default State
+
+Every workspace starts with:
+
+```typescript
+{
+  root: { kind: "pane", pane: { id: "main", tabIds: [], focusedTabId: null } },
+  focusedPaneId: "main",
+}
+```
+
+### Migration
+
+Version 6 migration from the current flat tab store. Wraps existing `tabIds`, `tabOrder`, and `focusedTabId` into a single-pane tree.
+
+## Store Actions
+
+### Everyday Operations (pane-agnostic)
+
+These don't take a `paneId`. Mobile code only uses these.
+
+```typescript
+openTab(workspaceKey: string, target: WorkspaceTabTarget): string | null;
+closeTab(workspaceKey: string, tabId: string): void;
+focusTab(workspaceKey: string, tabId: string): void;
+retargetTab(workspaceKey: string, tabId: string, target: WorkspaceTabTarget): string | null;
+reorderTabs(workspaceKey: string, tabIds: string[]): void;  // within focused pane
+getWorkspaceTabs(workspaceKey: string): WorkspaceTab[];      // all tabs across all panes
+```
+
+- `openTab` creates the tab and adds it to the focused pane.
+- `closeTab` finds the tab in any pane, removes it. If that was the last tab in the pane, collapses the pane.
+- `focusTab` finds the tab in any pane, focuses it and focuses that pane.
+
+### Split Operations (desktop only)
+
+```typescript
+splitPane(workspaceKey: string, input: {
+  tabId: string;
+  targetPaneId: string;
+  position: "left" | "right" | "top" | "bottom";
+}): string | null;  // new pane ID, or null if depth cap hit
+
+moveTabToPane(workspaceKey: string, tabId: string, toPaneId: string): void;
+focusPane(workspaceKey: string, paneId: string): void;
+resizeSplit(workspaceKey: string, groupId: string, sizes: number[]): void;
+reorderTabsInPane(workspaceKey: string, paneId: string, tabIds: string[]): void;
+```
+
+## Tree Transformations
+
+### splitPane
+
+**Position mapping:**
+- `left` / `right` → `horizontal` direction
+- `top` / `bottom` → `vertical` direction
+- `left` / `top` → new pane inserted before target
+- `right` / `bottom` → new pane inserted after target
+
+**Optimization:** If the target pane's parent group has the same direction, insert as a sibling into that group instead of nesting. This keeps the tree flat.
+
+```
+Before: horizontal([A, B])
+Split B right with tab X
+
+Optimized: horizontal([A, B, C])       ← insert into existing group
+Naive:     horizontal([A, horizontal([B, C])])  ← wastes depth
+```
+
+**Steps:**
+1. Check depth — reject if would exceed 4 levels
+2. Remove `tabId` from source pane (could be same or different pane)
+3. Create new pane: `{ id: generateId(), tabIds: [tabId], focusedTabId: tabId }`
+4. If parent group has same direction → insert new pane adjacent to target in parent's children, split target's size proportion 50/50 between target and new pane
+5. Else → replace target node with new group `{ direction, children: [target, newPane], sizes: [0.5, 0.5] }` (order based on position)
+6. If source pane is now empty → collapse it
+7. Set `focusedPaneId` to new pane
+
+### collapsePane
+
+Triggered when a pane's last tab is removed or moved out.
+
+```
+Before: horizontal([A, B, C]) sizes [0.3, 0.4, 0.3]
+B loses last tab
+
+After:  horizontal([A, C]) sizes [0.5, 0.5]  (renormalized)
+```
+
+**Steps:**
+1. Remove pane from parent group's children
+2. Remove corresponding entry from parent's sizes
+3. Renormalize sizes to sum to 1
+4. If parent group now has 1 child → unwrap: replace group with its single remaining child
+5. Unwrap can cascade up the tree
+6. Move focus to nearest sibling
+
+### moveTabToPane
+
+Tab dragged from one pane to another existing pane.
+
+1. Remove `tabId` from source pane's `tabIds`
+2. Insert into target pane's `tabIds` at drop position (or end)
+3. Set target pane's `focusedTabId` to the moved tab
+4. If source pane is now empty → collapsePane
+5. Set `focusedPaneId` to target pane
+
+### resizeSplit
+
+User drags a divider between panes.
+
+1. Find group by ID
+2. Update the two adjacent sizes based on drag delta
+3. Clamp each child to minimum proportion (0.1)
+4. Renormalize so sizes sum to 1
+

+| Action | Shortcut |
+|---|---|
+| Split right | `Cmd+\` |
+| Split down | `Cmd+Shift+\` |
+| Focus pane left | `Cmd+Shift+←` |

+Existing tab shortcuts unchanged — `Cmd+T`, `Cmd+W`, `Alt+Shift+[/]`, `Alt+1-9` — they operate on the focused pane's tabs.
+
+## Drag and Drop UX
+
+### Drop Zones
+
+When dragging a tab over a pane, the pane is divided into 5 drop zones:
+- **Center** (inner 40%) — move tab to this pane (add to existing tab list)
+- **Left edge** (leftmost 15%) — split left
+- **Right edge** (rightmost 15%) — split right
+- **Top edge** (topmost 15%) — split up
+- **Bottom edge** (bottommost 15%) — split down
+
+### Overlay Preview
+
+On hover over a drop zone, show a semi-transparent overlay rectangle covering the half of the pane where the new split would appear. The overlay uses the theme's accent color at low opacity.
+
+### Cross-Pane Tab Drag
+
+Tabs can be dragged:
+- Within a pane's tab bar → reorder (existing behavior via SortableInlineList)
+- From one pane's tab bar to another pane's tab bar → move tab to that pane
+- From a tab bar to a pane's drop zone → split
+
+When dragging the last tab out of a pane, the pane collapses after the drop completes.
+
+## Implementation Steps
+
+### Step 1: Layout Store
+
+Create `packages/app/src/stores/workspace-layout-store.ts`:
+- `WorkspaceLayout`, `SplitNode`, `SplitPane`, `SplitGroup` types
+- Zustand store with AsyncStorage persistence
+- Everyday actions: `openTab`, `closeTab`, `focusTab`, `retargetTab`, `reorderTabs`
+- Tree helpers: `findPaneById`, `findPaneContainingTab`, `getTreeDepth`, `collectAllTabs`
+- Version 6 migration from flat tab store
+
+### Step 2: Migrate Workspace Screen to Layout Store
+
+Replace all `useWorkspaceTabsStore` usage in workspace-screen with the new layout store. Mobile and desktop both use the layout store — mobile just never splits. All existing behavior preserved.
+
+### Step 3: Split Tree Transformations
+
+Add to the layout store:
+- `splitPane` with the parent-direction optimization and depth check
+- `collapsePane` with unwrap cascading
+- `moveTabToPane`
+- `resizeSplit`
+
+Pure tree transformation functions, tested independently.
+
+### Step 4: Split Container Component
+
+Create `packages/app/src/components/split-container.tsx`:
+- Recursive component that renders `SplitNode`
+- Groups render as flex containers with direction from `SplitGroup.direction`
+- Panes render tab bar + active panel content (using the panel registry)
+- Resize handles between children of a group
+
+### Step 5: Drop Zones and Overlay
+
+Create `packages/app/src/components/split-drop-zone.tsx`:
+- Overlay that appears during tab drag
+- Divides pane into 5 zones (center + 4 edges)
+- Shows preview rectangle on hover
+- Calls `splitPane` or `moveTabToPane` on drop
+
+### Step 6: Cross-Pane Drag
+
+Extend the existing dnd-kit setup:
+- Tab bar items remain draggable (existing)
+- Pane drop zones become droppable targets
+- Tab bar of other panes become droppable targets (move to pane)
+- DndContext wraps the entire split container (not individual panes)
+
+### Step 7: Keyboard Shortcuts
+
+Register new actions in `keyboard/actions.ts`:
+- `workspace.pane.split.right`, `workspace.pane.split.down`
+- `workspace.pane.focus.left/right/up/down`
+- `workspace.pane.move-tab.left/right/up/down`
+- `workspace.pane.close`
+
+Add bindings in `keyboard-shortcuts.ts` and handlers in the workspace screen.
+
+### Step 8: Pane Focus Navigation
+
+Implement spatial navigation for `focus.left/right/up/down`:
+- Walk the tree to find the focused pane's position in the layout
+- Find the nearest pane in the requested direction
+- Focus it
+
+Same logic for `move-tab` shortcuts — find adjacent pane, call `moveTabToPane`.
+
+## Constraints
+
+- Mobile stays single-pane — same store, no special casing
+- Max 4 levels of nesting
+- Minimum pane size: 10% of parent
+- `PaneContext` interface unchanged — no `paneId` added
+- Panel registry unchanged — panels don't know about splits
+- Existing tab shortcuts work on focused pane, unchanged

-Find ONE failing test across the entire repo and fix it.
-
-The objective: get CI green on GitHub Actions. The build has been red for ages and it's embarrassing. Not all tests can run in GH Actions but MOST of them should.
-
-Use --bail 1 / --max-failures 1 / fail-fast ALWAYS. Do not run the whole suite. Find the first failure FAST.
-
-Auth is fully configured: CLAUDE_CODE_OAUTH_TOKEN and OPENAI_API_KEY are set. OpenCode uses free models needing no auth. All three providers work. There is zero reason to check for auth or skip tests based on environment.
-
-Work across all packages — server unit tests, server e2e, daemon tests, app unit tests, Playwright browser e2e, CLI integration tests. All of them.
-
-When a test fails:
-- Outdated (tests removed/renamed APIs) → fix or delete if unnecessary
-- Flaky (races, timing) → make it deterministic
-- Too slow → make it fast or delete
-
-Do NOT weaken tests. Do NOT add conditionals. Do NOT introduce mocks — we use real environment on purpose because we want to test the REAL thing. Do NOT add auth gating or skip conditions. Do NOT implement new features to make a test pass. You are here to fix tests, not build features. If a test expects unimplemented behavior, delete it.
-
-While you're in a file, improve it:
-- Refactor repeated code RUTHLESSLY. Extract shared helpers across test files.
-- Simplify complex tests. Tests should read almost like plain English.
-
-Test philosophy for this project:
-- What we love: general e2e tests that test as close to the user as possible. CLI tests against a real daemon. E2E tests against a real daemon. Playwright browser tests. These are the most valuable.
-- Unit tests are for pure functions and specific provider functionality.
-- If a test doesn't add real value, delete it. Don't preserve tests for coverage theater.
-
-Resource hygiene:
-- Many tests spawn temporary daemons or do heavy setup. Pay attention to cleanup.
-- Make sure cleanup works consistently and runs even on failure.
-- When killing processes, ensure you're ONLY killing test processes that YOU ran. Use PIDs, not broad patterns.
-
-After changes: run typecheck (npm run typecheck --workspaces --if-present).
-
-Skip *.real.e2e.test.ts and *.local.e2e.test.ts (local-only manual testing).
