feat: add approve/shutdown REST routes, fix WS status updates, revise README

- Add POST /api/tasks/:id/approve, /api/approve-all, /api/shutdown routes
  that the CLI already calls but were missing from the router
- Fix WebSocket TaskApprove/TaskApproveAll handlers to update task status
  from "input" to "running" in the database (was only writing to PTY)
- Use two-phase lock pattern: update DB while holding lock, then drop
  before async PTY writes
- Revise README: mark Docker isolation as planned, update iTerm2 section
  to reflect WebSocket API (not bridge scripts), update test counts,
  fix roadmap to v0.1.0-alpha with accurate feature list
- 8 new handler tests covering approve, approve-all, and shutdown
