Goal prompt

/goal Implement the Jackin Desktop Agent Hub end to end as a long-running staged program.

Context:
- Build the full desktop experience described in the roadmap: daemon APIs,
  native macOS status bar, native desktop app/window, Ghostty workspace
  launch/focus actions, GitHub PR inbox, account/token status for
  Claude/Codex/Amp, and notification/attention support.
- Work in the jackin repo. PR 283 is an editable daemon draft: if the Desktop
  goal reveals daemon API changes that should land there, update that PR
  directly before stacking later Desktop PRs. New agent-created PRs still target
  `main` unless the operator explicitly names a different base branch; follow
  PULL_REQUESTS.md for the base-branch rule.
- Read the roadmap source of truth first. If implementation details conflict
  with these docs, update the relevant roadmap doc in the same PR or an earlier
  stacked PR before coding around the conflict:
  - docs/src/content/docs/reference/roadmap.mdx
  - docs/src/content/docs/reference/roadmap/jackin-desktop-agent-hub.mdx
  - docs/src/content/docs/reference/roadmap/jackin-daemon.mdx
  - docs/src/content/docs/reference/roadmap/live-auth-sync.mdx
  - docs/src/content/docs/reference/roadmap/agent-attention-prompts.mdx
  - docs/src/content/docs/reference/roadmap/host-bridge.mdx
  - docs/src/content/docs/reference/roadmap/github-link-tracking.mdx
  - docs/src/content/docs/reference/roadmap/agent-runtime-status.mdx
  - docs/src/content/docs/reference/roadmap/token-cost-telemetry.mdx
  - docs/src/content/docs/reference/roadmap/agent-orchestrator-research.mdx
- Read the daemon implementation in src/daemon.rs and launch integration in
  src/runtime/launch.rs.
- Read the existing workspace manager model/render/input paths under src/console/manager for vocabulary and workspace semantics only. Do not port the full TUI editor into the macOS v1.
- Research steipete/CodexBar and steipete/RepoBar as prototypes, but do not copy
  their broad implementation. Borrow only the useful native macOS patterns:
  menu bar controller, refresh loop, provider/account cards, repository/PR menu
  organization, local git status caching.

Product goal:
Build the complete native macOS desktop companion while keeping the agent TUI as
the primary agent UI. Desktop must be an operator control surface with
daemon-backed state, native status bar, native desktop window, active Jackin
workspaces, simple Ghostty launches, recently active GitHub projects, workspace
repositories, running isolated agents, PR jump links, newest-first open PRs
authored by the operator, org/project-filtered PR inbox views, account/quota
status for Claude/Codex/Amp, and daemon-driven notifications plus
attention/ready-for-review events.

Constraints:
- Native macOS only for the app: SwiftUI/AppKit, MenuBarExtra or NSStatusItem,
  standard macOS controls, Liquid Glass where system components provide it.
- Jackin CLI/TUI remains usable without the app.
- The app requires a compatible jackin CLI/daemon and talks through a versioned
  daemon protocol.
- Do not build a replacement UI for Claude Code, Codex, or Amp.
- Do not implement generic provider support beyond Claude, Codex, Amp.
- Do not make Desktop parse Jackin TOML directly. Prefer daemon endpoints for
  data and status. Use CLI/library calls only for fallback, install/bootstrap,
  or one-shot actions where daemon communication would hurt the user
  experience.
- Do not port the full `jackin console` workspace editor in v1. The macOS app
  lists and launches existing workspaces only.
- Use Ghostty only for v1 launch/hardline actions. Other terminal adapters are
  deferred.
- Work autonomously and silently. Do not ask the operator for approval between
  implementation steps unless CI, conflicts, credentials, or a roadmap
  contradiction blocks progress.
- Before opening or updating any PR, read and follow AGENTS.md,
  PULL_REQUESTS.md, and COMMITS.md. Match the repository's established PR body,
  commit format, DCO signoff, and agent co-author trailer rules.
- Do not create one huge pull request. Implement the goal as small sequential
  PRs. Each PR must be reviewable, tested, and mergeable before the next PR
  becomes the main review target.
- Keep implementing the full staged plan until every Desktop Agent Hub stage is
  represented by reviewable PRs: daemon, status bar, desktop window, GitHub PR
  views, account status, Ghostty actions, notifications, and attention routing.
  Do not stop after the first slice unless blocked by CI, credentials, conflicts,
  or a roadmap contradiction that must be resolved first.
- Open every planned PR without waiting for operator approval, but never merge
  any PR. The operator will review and merge gradually.
- Stack each next PR by branching from the previous PR branch. If an earlier PR
  changes during review, update that PR and then rebase or adjust every
  downstream PR so the chain remains ordered.
- Make the chain explicit in each PR body: previous PR, current slice, next
  planned PR, and the correct review order.

Sequential PR plan:
1. Daemon capability handshake and protocol scaffolding.
2. Session/workspace discovery with labels and tests.
3. GitHub PR lookup endpoints: `github/my_open_prs`, `github/project_inbox`,
   and `github/repository_prs`.
4. Ghostty launch/open action contract for `workspace/launch` and
   `desktop/open`.
5. Account status endpoints for Claude, Codex, and Amp with cache/refresh
   semantics.
6. Native macOS app skeleton with menu bar daemon health.
7. Menu bar active workspaces and running-agent counts.
8. Menu bar PR/project inbox and open actions.
9. Simple desktop window shell.
10. Desktop Pull Requests and Projects views with org/project filters.
11. Desktop Workspaces launch-only view and Running Agents view.
12. Attention/ready-for-review promotion and notification click routing.

Start with this implementation slice:
1. Strengthen PR 283 daemon protocol with a hello/capabilities response.
2. Add the smallest endpoint scaffolding needed to prove versioned requests and
   responses without implementing the whole Desktop backend in one PR.
3. Add focused tests for protocol compatibility and failure cases.
4. Open a small PR with the standard Jackin PR body and keep the next planned PR
   listed in the description.

Later daemon slices:
- Add read-only daemon endpoints:
   - workspace/list
   - session/list
   - workspace/launch
   - desktop/open for Ghostty and browser actions
   - github/my_open_prs
   - github/project_inbox
   - github/repository_prs
   - event/subscribe or a clearly scoped placeholder if streaming is too large
- Add missing Docker labels at role launch so session/list can identify
   workspace, role, agent, branch, and primary repo.
- Add a cache-first PR lookup path that can list open PRs authored by the
   operator, sorted by created date descending, scoped initially to recently
   active Jackin projects and workspaces.
- Add a simple workspace launch action that opens Ghostty and runs the selected
   saved workspace.
- Add tests for protocol compatibility, session discovery, PR sorting, and
   project filtering.
- Update docs with the daemon API contract and Desktop MVP plan as the contract
  becomes concrete.

Deliverables:
- A chain of small sequential PRs, each with passing focused tests and a clear
  next-PR pointer.
- A daemon API contract that becomes concrete over several reviewable slices.
- A concise implementation report on every PR with remaining risks, especially
  Amp account status and macOS app packaging/version negotiation.
