Implement enhanced build orchestration and artifact management

- Add build status tracking with state machine
- Implement build logging and monitoring system
- Add build progress tracking and cancellation support
- Create artifact management system with SQLite database
- Fix stage file extensions for proper Python imports
- Enhance resource allocation with actual resource tracking
- Add comprehensive testing for all components
