Make workspace, agent, and schedule automation consistent (#2186)

* feat(workspaces): align agent and schedule automation Make workspace identity the shared placement boundary for MCP and CLI, while caller identity determines parentage. Keep heartbeats minimal and cron-based without changing legacy rolling interval semantics. * test(cli): expect canonical schedule cadence * fix(automation): preserve workspace and schedule compatibility * fix(automation): preserve compatibility edges * fix(workspaces): align MCP lifecycle resolution * fix(workspaces): preserve creation intent * fix(workspaces): preserve branch and schedule identity

 ## Relationships

-Agents can launch other agents via the agent-scoped `create_agent` MCP tool. Agent-scoped creation is always asynchronous. `relationship` and `workspace` are separate decisions:
-
- `relationship` decides whether the new agent belongs under the caller.
- `workspace` decides where the new agent lives and whether a new workspace/worktree is created.
-
-`relationship: { kind: "subagent" }` stamps the created agent with `paseo.parent-agent-id`, pointing back at the creating agent. The client surfaces that as `agent.parentAgentId`. This requires an agent-scoped MCP session.
-
-`relationship: { kind: "detached" }` creates a sibling/root agent (e.g. handoffs, fire-and-forget delegations). The daemon may still use the creating agent for cwd/config inheritance, but it does not write `paseo.parent-agent-id`.
+Agents can launch other agents via the agent-scoped `create_agent` MCP tool. Agent-scoped creation is always asynchronous and always stamps `paseo.parent-agent-id`, pointing back at the caller. Omit `workspaceId` to use the caller's workspace, or pass an existing workspace ID returned by `create_workspace`. Placement never changes parentage.

 - **Subagents** — exist as part of the creating agent's work, appear in that agent's subagent track, and are archived with it.
- **Detached agents** — stand on their own, do not appear in the creating agent's subagent track, and are not archived with it.
+- **Detached agents** — stand on their own after an explicit detach transition, do not appear in the former parent's subagent track, and are not archived with it.

-`workspace: { kind: "current" }` uses the caller's workspace and can optionally override the runtime cwd. It requires an agent-scoped MCP session. `workspace: { kind: "create", source: { kind: "directory" | "worktree", ... } }` creates a new workspace for the new agent; worktree creation goes through the Paseo worktree workflow and stamps the agent with that fresh workspace id.
+Runtime ownership is resolved from explicit workspace ID and caller context, never from `cwd`. Workspace creation is a separate operation with `local | worktree` isolation; agent creation only selects an existing workspace.

-Users can also detach an existing subagent from the subagents track. Detach removes the `paseo.parent-agent-id` label only: it does not stop, archive, move, or restart the agent. The agent keeps its current `cwd` and `workspaceId`, leaves the former parent's track, and behaves like a root agent for tab close, workspace activity, and future parent archive.
+Users can also detach an existing subagent from the subagents track. Detach is deliberately a manual lifecycle gesture, not an agent-facing MCP tool.

The agent keeps its current `cwd` and `workspaceId`, leaves the former parent's track, and behaves like a root agent for tab close, workspace activity, and future parent archive.

 `notifyOnFinish` defaults to `true` for agent-scoped creation and background prompt follow-ups because most delegated work needs to report back to the creating agent. Set it to `false` only for truly fire-and-forget agents or prompts.

A transient setup input, also remembered as a create-form preference; it is not a workspace property. UI: "Isolation" control on the New Workspace screen. Code: `isolation` (`"local" | "worktree"`), `useWorkspaceIsolation` (`packages/app/src/screens/new-workspace-screen.tsx`); persisted as `FormPreferences.isolation` (`packages/app/src/create-agent-preferences/preferences.ts`). Distinct from **Workspace kind**, which is the git-derived property the intent produces (Local → `local_checkout` or `directory` by git-ness; New worktree → `worktree`). On the wire it is the create request's `source.kind` (`directory | worktree`, `packages/protocol/src/messages.ts:1693`).
 - **Agent** — See **Agent session**. UI still says "Agent" / "New Agent" in places, but moving toward **Agent session** as the canonical term. Code: `AgentSnapshotPayload` (`packages/protocol/src/messages.ts:608`). Forbidden: "Task", "Job", "Run".

 - **Forge** — Git hosting service behind Paseo's change-request features: GitHub, GitLab, Gitea, Forgejo, or a future registered adapter. Code: `ForgeService`, `forge-registry`, `forge-resolver`. Use `forge` for internal abstraction and registry IDs; use concrete forge names only when a behavior or RPC is forge-specific.
 - **Change request** — Forge-neutral term for a proposed branch-to-branch code change. UI normally renders the forge noun instead: GitHub/Gitea/Forgejo "PR", GitLab "MR". Code: `forge_change_request` attachments, `checkoutSource: { kind: "change_request" }`, and PR/MR status payloads.
 - **MR** — GitLab merge request. UI label for GitLab change requests only; do not use MR for GitHub/Gitea/Forgejo.
- **Worktree** — Paseo-managed git worktree (`~/.paseo/worktrees/{name}`); also a `workspaceKind` value. UI: CLI + `paseo.json` keys (`worktree.setup`, `worktree.teardown`) only. Code: `ProjectCheckoutLiteGitPaseoPayload` (`packages/protocol/src/messages.ts:2092`); CLI `paseo worktree` (`packages/cli/src/commands/worktree/index.ts:8`). Forbidden: "Checkout" as a synonym.
+- **Worktree** — Paseo-managed git worktree (`~/.paseo/worktrees/{name}`); also a `workspaceKind` value. User-facing creation treats it as the `worktree` workspace isolation choice. Code and `paseo.json` retain worktree terminology for git lifecycle implementation. Forbidden: "Checkout" as a product synonym.
 - **Repository / Remote** — Internal Git observations. They may affect mutable kind/branch metadata but never project identity, root, display name, or workspace membership. No UI label.
 - **Directory-backed surface** — A right-sidebar surface whose content is determined by the workspace's `cwd`, so two workspaces on the same directory see identical content: git diff/status, forge change-request info, file preview/explorer contents. Keyed by `(serverId, cwd)`, never `workspaceId`. See [architecture.md](architecture.md#right-sidebar-boundary-directory-backed-vs-workspace-owned).
 - **Workspace-owned state** — Per-workspace state that never leaks to a same-`cwd` sibling: tabs, agents, terminals, panes, title, plus review drafts, diff-mode overrides, composer attachments, and file-explorer open/expand state. Keyed by `workspaceId` (`cwd` only as a fallback for old payloads). See [architecture.md](architecture.md#right-sidebar-boundary-directory-backed-vs-workspace-owned).

 - **Terminal** — Workspace-scoped PTY shell streamed over the binary mux channel. UI: "Terminal". Code: `TerminalStreamFrame` (`packages/protocol/src/terminal-stream-protocol.ts`).
 - **Schedule** — Cron-style trigger that creates new agents. UI: CLI/MCP (`paseo schedule`, `create_schedule`). Don't confuse with: Heartbeat (cron prompt back into the same agent) or Loop (iterative re-execution of one agent).
- **Heartbeat** — Cron-style prompt sent back into the same agent/conversation. MCP: `create_heartbeat`. Use for reminders and babysitting where the status should return inline.
+- **Heartbeat** — Ephemeral cron prompt sent back into the same agent/conversation. Agent surfaces expose create, update cron, and delete only. Use for reminders and babysitting where status should return inline.
 - **Mode** — Provider-specific operational mode (plan, default, full-access, …). UI: icon-only. Code: `modeId` in `AgentSessionConfig` (`packages/protocol/src/messages.ts:257`).
 - **Attachment** — External or local context bound to an agent prompt: forge issue/change request, review context, uploaded file, text, or image. UI: "Attach issue or PR/MR". Code: `AgentAttachment` (`packages/protocol/src/messages.ts:782`).
 - **Composer** — The whole prompt surface for sending work to an agent. Code: `Composer` (`packages/app/src/composer/index.tsx`). Don't call this "message input" except for the text-entry subcomponent.

-Use `workspace` for placement:
+1. Select the current workspace or call `create_workspace` with the requested isolation.
+2. Call `create_agent` with a `[Handoff] <task>` title, the briefing as initial prompt, and the selected `workspaceId` when explicit placement is needed.
+3. Return the agent and workspace to the user, explaining that it remains in your subagent track until they detach it manually.

- No worktree: `workspace: { kind: "current" }`.
- Worktree: `workspace: { kind: "create", source: { kind: "worktree", target: { kind: "branch-off", worktreeSlug: "<short-task-slug>", branchName: "fix/<short-task-slug>" } } }`.
- Existing worktree already created by `create_worktree`: `workspace: { kind: "existing", workspaceId: "<returned-workspace-id>" }`.
-
-Do not use `workspace: { kind: "current", cwd: "<worktreePath>" }` to place a handoff in a worktree; that keeps the agent in the caller's workspace with only a different runtime cwd.
+Do not encode independence as a create mode and do not invoke CLI or wire-level detach operations. Detach is a user gesture in the subagents track.

 Leave `notifyOnFinish` omitted unless the user explicitly wants no callback.

-## Worktrees
+## Workspaces

-**`create_worktree`** — same target union as `create_agent.workspace.source.worktree.target`:
+**`create_workspace`** — create a workspace independently of any agent. Required: `isolation` (`local` or `worktree`). Worktree isolation supports `mode: "branch-off" | "checkout-branch" | "checkout-pr"`: use `branchName`/`baseBranch` for a new branch, `branch` for an existing branch, or `prNumber` plus optional `forge`/`projectPath` for a change request. `worktreeSlug` controls the managed path. Returns the workspace descriptor centered on `workspaceId`.

- From a PR: `{ target: { kind: "checkout-pr", githubPrNumber: 503 } }`.
- Branch off a base: `{ target: { kind: "branch-off", worktreeSlug: "foo", branchName: "fix/foo", baseBranch: "main" } }`.
- Checkout an existing branch: `{ target: { kind: "checkout-branch", branch: "feat/bar" } }`.
+**`list_workspaces`** — list active workspaces.

-Returns `{ branchName, worktreePath, workspaceId }`. Pass `cwd` to target a specific repo.
+**`archive_workspace`** — `{ workspaceId }`. Archives the workspace, its agents, and its terminals. Local directories remain; Paseo removes an owned worktree only after its final active workspace reference is archived.

-In `branch-off`, `worktreeSlug` controls the worktree path slug and `branchName` controls the git branch. If `branchName` is omitted, Paseo defaults it from `worktreeSlug`. The returned `branchName` is authoritative; checkout and PR flows may return a branch name that differs from any requested slug.
-
-**`list_worktrees`** — current repo (or pass `cwd`).
-**`archive_worktree`** — `{ worktreePath }` or `{ worktreeSlug }`. Removes worktree and branch.
+Worktree creation and reference accounting are implementation details of `isolation: "worktree"`.

 ## Agents

-**`create_agent`** — required: `relationship`, `workspace`, `title`, `provider` (`claude/opus`, `codex/gpt-5.4`, …), `initialPrompt`. Common: `notifyOnFinish`, `settings`, `labels`. Returns `{ agentId, … }`.
+**`create_agent`** — required: `title`, `provider` (`claude/opus`, `codex/gpt-5.4`, …), `initialPrompt`. Optional: `workspaceId`, `notifyOnFinish`, `settings`, `labels`. Returns `{ agentId, workspaceId, … }`.

 Initial runtime settings live under `settings`: `modeId`, `thinkingOptionId`, and provider-specific `features`. For Codex fast mode, pass `settings: { features: { "fast_mode": true } }` when creating the agent.

-To create a new worktree and launch an agent in it, use `create_agent.workspace.source.kind = "worktree"`. Use `create_worktree` separately only when you need a worktree without launching an agent, or when you need a split flow; in a split flow, pass the returned `workspaceId` to `create_agent` with `workspace: { kind: "existing", workspaceId }`.
+Agent-scoped creation always creates your subagent. Omit `workspaceId` to use your current workspace; pass a workspace returned by `create_workspace` for isolated delegation. Placement never changes parentage.

-### Agent relationships
-
-`relationship` controls parentage only:
-
- `{ kind: "subagent" }` — child under your subagents track. Use for advisors, committee members, planners, implementers, auditors, loop workers, and any agent whose lifetime belongs to your task.
- `{ kind: "detached" }` — root/sibling agent. Use for handoffs and fire-and-forget delegations the user may continue after you are archived.
-
-`workspace` controls placement only:
-
- `{ kind: "current" }` — same workspace as the caller, with optional `cwd`.
- `{ kind: "existing", workspaceId: string, cwd?: string }` — attach to an existing workspace, usually from `create_worktree`.
- `{ kind: "create", source: { kind: "directory", path?: string } }` — new workspace rooted at a directory.
- `{ kind: "create", source: { kind: "worktree", cwd?: string, target: { kind: "branch-off", worktreeSlug?: string, branchName?: string, baseBranch?: string } } }`
- `{ kind: "create", source: { kind: "worktree", cwd?: string, target: { kind: "checkout-branch", branch: string } } }`
- `{ kind: "create", source: { kind: "worktree", cwd?: string, target: { kind: "checkout-pr", githubPrNumber: number } } }`
+Detach is an explicit user action in the subagents track, not an agent tool. A cross-workspace child remains your subagent even though it also appears as a normal tab in its workspace.

 Agent-scoped `create_agent` defaults `notifyOnFinish` to true. Set it to `false` only for truly fire-and-forget agents.
