- Refactor monolithic Flask app into separate processes:
  * Web interface process (vidai/web.py)
  * Backend routing process (vidai/backend.py)
  * Analysis worker processes (vidai/worker_analysis.py)
  * Training worker processes (vidai/worker_training.py)

- Add self-contained inter-process communication using TCP sockets
- Implement configuration system for backend selection (CUDA/ROCm)
- Add GPLv3 licensing and copyright notices
- Create comprehensive documentation and build scripts
- Update main launcher to manage all processes

This architecture provides better scalability, allows independent GPU backend selection, and maintains clean separation of concerns.
