feat: priority system, batch tasks, action feedback, event daemon

- Priority system: GET /api/state/priorities, POST /api/action/priority_global, POST /api/action/priority_type
- Batch system: POST /api/action/batch with per-action result tracking
- Enhanced action feedback with error codes and AI suggestions:
  cell_occupied, cell_solid, cell_occupied_by_dupe, material_shortage, etc.
- Event stream: GET /api/state/events?since=&limit= for incremental polling
- Event daemon: scripts/event_daemon.py continuously polls events,
  classifies by severity, auto-triggers analysis on critical events
- Games state now reports suffocating/starving/stressed counts
- Cell data includes isDiggable and isSafeForDupe flags
- Added 'events', 'queue', 'batch', 'priority_global', 'priority_type' CLI commands
- Added sample batch plan file
