feat: Add VRM Blender addon with complete import/export functionality
- Add core VRM addon infrastructure with manifest and registration - Add common utilities module with file system, logging, and conversion helpers - Add human bone mapper with support for multiple rigging standards (Mixamo, MMD, Unreal, Rigify, etc.) - Add VRM 0.x and 1.x format support with property groups and handlers - Add editor UI panels for VRM metadata, spring bones, and MToon materials - Add exporter with glTF2 extension support for VRM format serialization - Add importer with scene reconstruction and armature generation - Add MToon shader support with auto-setup and material migration - Add spring bone physics simulation with constraint handling - Add node constraint editor for advanced rigging control - Add comprehensive validation and error handling with user dialogs - Add scene watcher for real-time property synchronization - Add workspace management and preference system - Include Python cache files and Blender manifest configuration - This is the initial commit establishing the complete VRM addon ecosystem for Blender
