feat: integrate Analyst into Plane/Orchestrator pipeline

- Add git fetch+checkout in agent launch cmd (ensures correct branch)
- Add git fetch+checkout in _monitor_agent before commit/push
- Post start comment in Plane when analyst launches
- Post :approved: request comment after analyst completes successfully
- Branch lookup moved before cmd construction for reuse
