Randall Stillwell 778fe1d321 plans: scaffold daily-driver-finish, saas-hardening, agent-coordination
Three new plan trees that fill in the gaps surfaced during repo review.
Together they map out what remains between the current scaffold-with-stubs
state and a daily-usable, multitenant, agent-coordinated app.

* Plan-daily-driver-finish (P0): turn stubs into real data. Five tasks
  covering the lint/shared-types breakage, hardcoded dashboard mocks,
  AI-page setTimeout placeholder, post-signin landing decision, and a
  cross-browser collab smoke test against the deployed Hocuspocus
  instance.

* Plan-multitenant-saas-hardening (P1): everything multitenant needs
  beyond what Plan-multitenant-cursor-sync already covers. Invites and
  role management, soft-delete + append-only audit log, rate limits on
  the auth + mutation hot paths, and a Vitest + GitHub Actions test
  foundation so PRs can't ship red.

* Plan-agent-coordination (P2): the layer that makes a Task-*.md
  runnable, not just readable. Adds workflow_prompt with task -> epic
  -> plan inheritance, an agent_runs table for auditable sessions, and
  two new MCP tools (claim_task / complete_task) that replace the
  freeform update_object composition agents do today. Includes an
  intentionally-deferred Epic-optional-orchestrator that captures the
  Symphony-shaped runner as a decision point rather than an immediate
  build.

Each task is bead-scale (one focused Cursor session) with explicit
in-scope, out-of-scope, and anti-goal sections so a future agent can
pick up a single Task-*.md and start without scrollback context.

# Epic objective
Add two MCP tools that give a coding agent a shaped lifecycle for a task: `claim_task` (status flip + open `agent_runs` row + return effective workflow prompt) and `complete_task` (status flip + close `agent_runs` row with outcome + tokens).
These replace the current freeform composition where an agent has to call `update_object` repeatedly and pray.
## In scope / out of scope
**In scope**
- New MCP tools `claim_task` and `complete_task` with zod schemas.
- Idempotency rules (don't double-claim).
- Integration with the `agent_runs` table from the previous epic.
**Out of scope**
- A long-running orchestrator (deferred epic).
- A `pause_task` / `resume_task` tool. Resist; you can model that with two `complete_task` calls (`cancelled` + a new claim) until evidence demands it.
## Related tasks
| Task | Link |
|------|------|
| MCP claim_task tool | `./Task-mcp-claim-task-tool.md` |
| MCP complete_task tool | `./Task-mcp-complete-task-tool.md` |
## Dependencies
- Depends on: `Epic-task-as-runnable-unit` (needs `workflow_prompt` and `agent_runs`).
## Acceptance criteria
- [ ] An agent can call `claim_task({ workspace, backlogItemId })` and receive the effective workflow prompt + a `runId`.
- [ ] An agent can call `complete_task({ runId, outcome, tokens, notes })` to finalize.
- [ ] Double-claim of the same task by the same actor returns the existing open run; by a different actor returns an explicit "already claimed by X" error.
## Proposed timeline
| Phase | Window | Notes |
|-------|--------|-------|
| claim_task | Day 1 | Tool + idempotency. |
| complete_task | Day 2 | Tool + run finalization. |
