Add semantic color system for containers and codecs
Implements professional color taxonomy based on NLE/broadcast conventions:
- Container colors (MKV teal, MP4 blue, MOV indigo, etc.)
- Video codec colors (AV1 emerald, HEVC lime, H.264 sky blue, etc.)
- Audio codec colors (Opus violet, AAC purple, FLAC magenta, etc.)
- Pixel format colors (yuv420p slate, HDR cyan, etc.)
Helper functions to retrieve colors by format/codec name.
