Initial implementation of DotLuxafor library and UI

- Add DotLuxafor .NET library for Luxafor device control via HIDSharp
- Provide async API for color, effects, per-LED, and event streaming
- Support device identification, multi-device, and DI integration (net8+)
- Implement Avalonia-based cross-platform control panel UI
- Add MVVM, themed UI, event log, and real-time device status
- Include comprehensive unit tests for all core features and DI
- Add build, code style, and GitHub Actions CI configuration
- Provide detailed README with usage and API documentation
