Initial commit: Desktop Waifu MVP foundation

- Project structure with modular architecture
- State management system (emotion states, conversation history)
- Transparent, draggable PyQt6 window
- OpenGL rendering widget with placeholder cube
- Discord bot framework (commands, event handlers)
- Complete documentation (README, project plan, research findings)
- Environment configuration template
- Dependencies defined in requirements.txt

MVP features working:
- Transparent window appears at bottom-right
- Window can be dragged around
- Placeholder 3D cube renders and rotates
- Emotion state changes on interaction
- Event-driven state management

Next steps: VRM model loading and rendering
