fix: Improve GitHub Actions workflows and add comprehensive tests

GitHub Actions improvements:
- Fix release workflow to prevent draft releases on new workflow runs
- Add automatic deletion of previous releases with same tag
- Improve test workflow with torrent-engine-downloads branch support
- Update Flutter version and add code generation step
- Add Android lint checks and debug APK builds
- Remove emoji from all workflow outputs for cleaner logs
- Add make_latest flag for proper release versioning

Test improvements:
- Add comprehensive unit tests for TorrentInfo model
- Add tests for FilePriority enum with comparison operators
- Add DownloadsProvider tests for utility methods
- Add widget tests for UI components and interactions
- Test video file detection and main file selection
- Test torrent state detection (downloading, paused, completed)
- Test byte formatting for file sizes and speeds

All tests validate the torrent downloads functionality
and ensure proper integration with Android engine.
