Stu 18a14c6020 Refactor to modular architecture with rainbow UI (v0.1.0-dev8) 
Major refactoring to improve code organization and enhance UI:

Architecture:
- Split monolithic main.go into modular internal/ package structure
- Created internal/logging for centralized logging system
- Created internal/modules for module handler functions
- Created internal/ui for UI components and layouts
- Created internal/utils for shared utility functions

UI Enhancements:
- Implemented rainbow gradient across 8 module buttons (violet→red)
- Increased module button text size to 20 for better readability
- Fixed text centering on module tiles
- Converted Simple/Advanced mode toggle to tabs to save vertical space
- Added vertical scrollbars to prevent UI overflow
- Added metadata copy button (📋) to copy all metadata to clipboard

Video Processing:
- Fixed aspect ratio conversion to default to center-crop behavior
- Added 6 aspect handling modes: Auto, Crop, Letterbox, Pillarbox, Blur Fill, Stretch
- Fixed blur fill to maintain source resolution with padding (no scaling)
- Ensured all FFmpeg filters produce even-numbered dimensions for H.264

Known Issues:
- WMV files still produce FFmpeg error 234 during aspect conversions
  (requires codec-specific handling in future update)
