fix: rebuild all MusicGen workflows with correct nodes and links

Fixed medium, small, and melody workflows:
- Replaced non-existent nodes with Musicgen_ from Sound Lab
- Added missing links arrays to connect nodes properly
- Updated all metadata and performance specs

Note: Melody workflow simplified to text-only as Sound Lab doesn't
currently support melody conditioning via audio input.
