Implement multi-scheme animation name mapper for Owen Animation System

- Added AnimationNameMapper class to handle conversion between different animation naming schemes (legacy, artist, hierarchical, semantic).
- Included methods for initialization, pattern matching, conversion, and validation of animation names.
- Developed comprehensive unit tests for the animation name converter and demo pages using Playwright.
- Created a Vite configuration for the demo application, including asset handling and optimization settings.
- Enhanced the demo with features for batch conversion, performance metrics, and responsive design.
