- Project CRUD REST API with proper error handling
- Per-project agent loop (mpsc + broadcast channels)
- LLM-driven plan generation and replan on user feedback
- SSH command execution with status streaming
- WebSocket real-time updates to frontend
- Four-zone UI: requirement, plan (left), execution (right), comment
