Phase 3: IPC layer

- Implement src/main/preload.ts with typed API bridge
  - Projects, sessions, messages CRUD
  - Chat send/interrupt
  - Workflow review/advance/permissions
  - Artifact read/write
  - Directory picker dialog
  - Claude message event subscription
- Implement src/main/ipc/handlers.ts
  - All IPC handlers with proper error handling
  - Message forwarding to renderer
  - Assistant message storage
- Update src/main/index.ts
  - Initialize database on startup
  - Register IPC handlers
  - Clean database close on exit
