test: final verification of unified release workflow

This should now successfully:
✅ Trigger on push to master
✅ Handle no existing tags (start from v0.0.0)
✅ Analyze all commits for semantic versioning
✅ Calculate v1.0.0 (first release with features)
✅ Build all platforms
✅ Create unified GitHub release

Expected result: SwingMusic v1.0.0 release with all packages!
