Add CoordinatorIntegrationModule providing REST API endpoints for the Python
coordinator to communicate with the NestJS API infrastructure:
- POST /coordinator/jobs - Create job from coordinator webhook events
- PATCH /coordinator/jobs/:id/status - Update job status (PENDING -> RUNNING)
- PATCH /coordinator/jobs/:id/progress - Update job progress percentage
- POST /coordinator/jobs/:id/complete - Mark job complete with results
- POST /coordinator/jobs/:id/fail - Mark job failed with gate results
- GET /coordinator/jobs/:id - Get job details with events and steps
- GET /coordinator/health - Integration health check
Integration features:
- Job creation dispatches to BullMQ queues
- Status updates emit JobEvents for audit logging
- Completion/failure events broadcast via Herald to Discord
- Status transition validation (PENDING -> QUEUED -> RUNNING -> COMPLETED/FAILED)
- Health check includes BullMQ connection status and queue counts
Also adds JOB_PROGRESS event type to event-types.ts for progress tracking.
