- Robot-client: TelemetryReporter collects system metrics (CPU, RAM, disk, WiFi)
and sends them to backend every 60s via WebSocket
- Robot-client: LogForwarder buffers Pino logs and flushes them in batches
every 5s to the backend via WebSocket
- Backend: HealthReport entity + HealthTelemetryService with alert thresholds
(CPU >80°C, RAM >90%, disk >90%, load >3.0, heap >85%)
- Backend: DeviceLog entity + LogIngestionService with EventEmitter2 for SSE
- Backend: REST endpoints GET /devices/:id/health/reports and /alerts
- Backend: REST endpoint GET /devices/:id/logs with filtering (level, logger, search)
- Backend: SSE endpoint GET /admin/logs/stream for real-time log streaming
- Migrations for health_reports and device_logs tables with proper indexes
