Implement Owen Animation System with core classes, loaders, and state handlers
- Added OwenSystemFactory for creating the animation system. - Introduced OwenAnimationContext to manage animations and states. - Created AnimationLoader and GLTFAnimationLoader for loading animations. - Developed state handlers: WaitStateHandler, ReactStateHandler, TypeStateHandler, SleepStateHandler. - Implemented StateFactory for managing state handlers. - Defined constants for clip types, states, and emotions. - Added type definitions for TypeScript support. - Configured Vite for building and serving the project. - Added licenses (dual) to project.
