Implement DVD-NTSC encoding support with multi-region capabilities
Add comprehensive DVD-Video encoding functionality:
- New internal/convert package with modular architecture
- types.go: Core types (VideoSource, ConvertConfig, FormatOption)
- ffmpeg.go: FFmpeg codec mapping and video probing
- presets.go: Output format definitions
- dvd.go: NTSC-specific DVD encoding and validation
- dvd_regions.go: PAL, SECAM, and multi-region support
- New internal/app/dvd_adapter.go for main.go integration
Features implemented:
✓ DVD-NTSC preset (720×480@29.97fps, MPEG-2/AC-3)
✓ Multi-region support (NTSC, PAL, SECAM - all region-free)
✓ Comprehensive validation system with actionable warnings
✓ Automatic framerate conversion (23.976p, 24p, 30p, 60p)
✓ Audio resampling to 48 kHz
✓ Aspect ratio handling (4:3, 16:9, letterboxing)
✓ Interlacing detection and preservation
✓ DVDStyler-compatible output (no re-encoding)
✓ PS2-safe bitrate limits (max 9000 kbps)

- DVD_IMPLEMENTATION_SUMMARY.md
All packages compile without errors or warnings.
Ready for integration with existing queue and UI systems.
