- Created clean module separation:
- SpineC: C/C++ compilation only (working)
- SpineSwift: Generated Swift bindings + platform-agnostic API
- SpineiOS: iOS-specific UI components only
- Updated Package.swift with proper target structure
- Moved generated Swift files to SpineSwift/Generated
- Removed redundant SpineModule
- Created test with skeleton_drawable_test.swift ported from Dart
- Test successfully runs using SpineC module directly
- Note: SpineSwift has Objective-C selector conflicts to be fixed
