- Add comprehensive production statistics engine with advanced analytics,
  forecasting, and OEE calculations
- Implement real-time WebSocket streaming for live device monitoring and alerts
- Build cache management service with multi-layer caching strategies
- Create device state machine with automatic validation and recovery
- Add statistics and configuration API controllers with full CRUD operations
- Implement business rules engine with dynamic expression evaluation
- Add comprehensive test coverage for all new services and controllers
- Update project dependencies and DI container configuration
- Add system configuration models and comprehensive error handling

This completes the core functionality for the CNC data collection system
supporting 100+ devices with real-time monitoring and analytics capabilities.
