fix: always use V2 lazy diff RPCs in new clients

Back-compat is old clients talking to new daemons, not the other way
around. New clients should always use the V2 lazy diff path — there's
no need to fall back to V1 based on a feature flag.

- Remove useLazyDiff feature gate from git-diff-pane
- Always use useCheckoutDiffMetadataQuery (V2)
- Remove useCheckoutDiffQuery (V1) usage from the component
- Remove supportsLazyDiffRpcs utility (no longer needed client-side)
- Server still advertises the flag and serves V1 for old clients

 # Changelog
 
+## 0.1.54 - 2026-04-12
+
+### Added
+- Inline image previews in agent messages — screenshots and images generated by agents render directly in the conversation instead of showing as raw markdown links.
+
+### Improved
+- Paseo tools are no longer injected into agents by default — opt in from Settings when you need agent-to-agent orchestration.
+- Agent provider and mode are now resolved server-side, so CLI commands like `paseo run` use consistent defaults without client-side lookups.
+
+### Fixed
+- Shift+Enter now correctly inserts a newline in agent terminal input instead of submitting.
+- Windows: MCP configuration is no longer mangled when spawning Claude agents.
+- Branch ahead/behind count no longer errors for branches with no remote tracking branch.
+
+## 0.1.53 - 2026-04-12
+
+### Added
+- Agents get Paseo tools automatically — every new agent gets access to terminals, schedules, worktrees, and other agents through MCP. Toggle it off in Settings under "Inject Paseo tools".
+- Git pull — pull remote changes directly from the workspace header. Promoted to the primary action when your branch is behind origin.
+- Child agent notifications — parent agents are automatically notified when a child agent finishes, errors, or needs permission approval.
+- Agent reload — `paseo agent reload` restarts an agent's underlying process from the CLI.
+- Middle-click to close tabs on desktop.
+- Keyboard shortcut to cycle themes.
+
+### Improved
+- Unavailable git actions now explain why in a toast instead of being silently greyed out.
+- Streaming markdown on mobile renders significantly faster.
+- Sidebar, branch switcher, and agent panel no longer re-render unnecessarily — noticeable on large workspaces.
+- Paseo tool calls in agent timelines show the Paseo logo and human-readable names.
+- Relay and pairing URLs are stripped from daemon logs.
+
+### Fixed
+- Closed agent tabs no longer reappear after reconnecting.
+- Desktop notification badge counts match across all workspaces.
+- Host switcher status syncs correctly when switching between hosts.
+

+## Platform gating
+
+The app runs on iOS, Android, web (browser), and web (Electron desktop). Code is cross-platform by default. Gate only when you must. Import gates from `@/constants/platform`.
+
+### The four gates
+
+| Gate | Type | When to use |
+|---|---|---|
+| `isWeb` | constant | DOM APIs — `document`, `window`, `<div>`, `addEventListener`, `ResizeObserver`. This is the **exception**, not the default. |
+| `isNative` | constant | Native-only APIs — Haptics, `StatusBar.currentHeight`, push tokens, camera/scanner, `expo-av`. |
+| `getIsElectron()` | cached fn | Desktop wrapper features — file dialogs, titlebar drag region, daemon management, app updates, dock badges. |
+| `useIsCompactFormFactor()` | hook | Layout decisions — sidebar overlay vs pinned, modal vs full screen, single-panel vs split. From `@/constants/layout`. |
+
+### Decision matrix
+
+| I need to... | Use |
+|---|---|
+| Access DOM (`document`, `window`, `<div>`, `addEventListener`) | `if (isWeb)` |
+| Use a native-only API (Haptics, push tokens, camera) | `if (isNative)` |
+| Use an Electron bridge (file dialog, titlebar, updates) | `if (getIsElectron())` |
+| Switch layout between phone and tablet/desktop | `useIsCompactFormFactor()` |
+| Show something on hover, always-visible on native | `isHovered \|\| isNative \|\| isCompact` (hover only works on web) |
+| Gate to iOS or Android specifically | `Platform.OS === "ios"` / `Platform.OS === "android"` (rare, keep inline) |
+
+### Rules
+
+- **Default is cross-platform.** Don't gate unless you have a specific reason.
+- **Prefer Metro file extensions over `if` statements.** When a module has fundamentally different implementations per platform, use `.web.ts` / `.native.ts` file extensions instead of runtime `if (isWeb)` branches. Metro resolves the correct file at build time — the unused platform code is never bundled. Reserve `if (isWeb)` for small, inline checks (a single line or a few props). If you find yourself writing a large `if (isWeb) { ... } else { ... }` block, split into separate files instead.
+  ```
+  hooks/
+    use-audio-recorder.web.ts    ← uses Web Audio API
+    use-audio-recorder.native.ts ← uses expo-audio
+  ```
+  Import as `@/hooks/use-audio-recorder` — Metro picks the right file automatically.
+- **NEVER use raw DOM APIs without `isWeb` guard.** DOM APIs crash native. Casting a RN ref to `HTMLElement` is a red flag — ensure the block is web-only.
+- **NEVER use `onPointerEnter`/`onPointerLeave`.** They don't fire on native iOS.
+- **Hover only works on web.** React Native's `onHoverIn`/`onHoverOut` on `Pressable` does NOT fire on native iOS/iPad — the underlying W3C pointer events are behind disabled experimental flags. For hover-to-show UI (kebab menus, action buttons), use `isHovered || isNative || isCompact` so the controls are always visible on native and hover-to-show on web.
+- **Don't use Platform.OS as a proxy for layout capabilities.** Use breakpoints for layout decisions, not platform checks.
+- **Import `isWeb`/`isNative` from `@/constants/platform`.** Never write `const isWeb = Platform.OS === "web"` locally.
+

+# Ad-hoc daemon testing
+
+Spin up an isolated daemon programmatically without touching the main daemon on port 6767.
+
+## Quick start
+
+```typescript
+import os from "node:os";
+import path from "node:path";
+import { mkdir, mkdtemp, rm } from "node:fs/promises";
+import pino from "pino";
+import { createPaseoDaemon } from "./bootstrap.js";
+import { DaemonClient } from "./test-utils/daemon-client.js";
+
+const logger = pino({ level: "warn" });
+const paseoHomeRoot = await mkdtemp(path.join(os.tmpdir(), "paseo-test-"));
+const paseoHome = path.join(paseoHomeRoot, ".paseo");
+await mkdir(paseoHome, { recursive: true });
+const staticDir = await mkdtemp(path.join(os.tmpdir(), "paseo-static-"));
+
+const daemon = await createPaseoDaemon(
+  {
+    listen: "127.0.0.1:0", // OS picks a free port
+    paseoHome,
+    corsAllowedOrigins: [],
+    allowedHosts: true,
+    mcpEnabled: false,
+    staticDir,
+    mcpDebug: false,
+    agentClients: {},
+    agentStoragePath: path.join(paseoHome, "agents"),
+    relayEnabled: false,
+    relayEndpoint: "relay.paseo.sh:443",
+    appBaseUrl: "https://app.paseo.sh",
+    // Add custom config here, e.g.:
+    // providerOverrides: { ... },
+  },
+  logger,
+);
+
+await daemon.start();
+const target = daemon.getListenTarget();
+const port = target!.type === "tcp" ? target!.port : null;
+
+const client = new DaemonClient({
+  url: `ws://127.0.0.1:${port}/ws`,
+  appVersion: "0.1.54", // see gotcha #1
+});
+await client.connect();
+await client.fetchAgents({ subscribe: { subscriptionId: "test" } });
+
+// ... do your testing ...
+
+await client.close();
+await daemon.stop();
+await rm(paseoHomeRoot, { recursive: true, force: true });
+await rm(staticDir, { recursive: true, force: true });
+```
+
+Run with:
+```bash
+npx tsx packages/server/src/server/your-script.ts
+```
+
+## Using the test helper
+
+For simpler cases, `createTestPaseoDaemon` + `DaemonClient` handles temp dirs and port selection:
+
+```typescript
+import { createTestPaseoDaemon } from "./test-utils/paseo-daemon.js";
+import { DaemonClient } from "./test-utils/daemon-client.js";
+
+const daemon = await createTestPaseoDaemon();
+const client = new DaemonClient({
+  url: `ws://127.0.0.1:${daemon.port}/ws`,
+  appVersion: "0.1.54",
+});
+await client.connect();
+await client.fetchAgents({ subscribe: { subscriptionId: "test" } });
+
+// ... test ...
+
+await client.close();
+await daemon.close(); // stops daemon + cleans up temp dirs
+```
+
+The test helper does **not** expose `providerOverrides`. Use `createPaseoDaemon` directly when you need it (see quick start above).
+
+## Common client methods
+
+```typescript
+// Provider discovery
+const snapshot = await client.getProvidersSnapshot({ cwd: "/tmp" });
+const models = await client.listProviderModels("claude");
+const modes = await client.listProviderModes("claude");
+
+// Agent lifecycle
+const agent = await client.createAgent({ provider: "claude", cwd: "/tmp" });
+await client.sendMessage(agent.id, "Hello");
+const updated = await client.waitForAgentUpsert(agent.id, (s) => s.status === "idle");
+```
+
+## Gotchas
+
+### 1. appVersion gates provider visibility
+
+The daemon hides non-legacy providers (anything other than claude, codex, opencode) from clients that don't send an `appVersion >= 0.1.45`. The `DaemonClient` sends no version by default, so custom providers like ACP-based ones will be invisible in snapshot responses.
+
+Always pass `appVersion`:
+```typescript
+const client = new DaemonClient({
+  url: `ws://127.0.0.1:${port}/ws`,
+  appVersion: "0.1.54",
+});
+```
+
+### 2. Provider snapshots are async
+
+After the daemon starts, providers are probed in the background. The first `getProvidersSnapshot()` call will likely return `status: "loading"` for most providers. Poll until the provider you care about is no longer loading:
+
+```typescript
+let snapshot = await client.getProvidersSnapshot({ cwd: "/tmp" });
+for (let i = 0; i < 20; i++) {
+  const entry = snapshot.entries.find((e) => e.provider === "gemini");
+  if (entry && entry.status !== "loading") break;
+  await new Promise((r) => setTimeout(r, 2_000));
+  snapshot = await client.getProvidersSnapshot({ cwd: "/tmp" });
+}
+```
+
+### 3. fetchAgents is required before most operations
+
+Call `client.fetchAgents()` after connecting. The daemon session expects this handshake before it processes other requests — without it, messages like `get_providers_snapshot_request` will silently hang.
+
+### 4. listen: "127.0.0.1:0" for port allocation
+
+Always use port `0` so the OS picks a free port. Never hardcode a port — it will collide with the main daemon or other test runs.
+
+### 5. Script must live inside packages/server
+
+The test utilities use relative imports through the TypeScript project. Place your script somewhere under `packages/server/src/` and import from there. Scripts outside the repo will fail with module resolution errors.
+
+### 6. Cleanup on failure
+
+Wrap your test logic in try/finally to ensure the daemon stops and temp dirs are cleaned up, even if an assertion fails:
+
+```typescript
+try {
+  // ... test logic ...
+} finally {
+  await client.close();
+  await daemon.stop().catch(() => undefined);
+  await rm(paseoHomeRoot, { recursive: true, force: true });
+}
+```
+
+### 7. ACP providers spawn real processes
+
+When testing ACP providers (e.g., Gemini with `extends: "acp"`), the daemon will spawn real processes to probe for models and modes. The binary must be installed and on PATH. Probing can take 5-15 seconds depending on the provider.
