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. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
