- 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.

+  - `AnimationClipFactory` - Animation creation with metadata parsing
+  - `StateHandler` - Abstract base for state implementations
+  - `StateFactory` - Dynamic state handler creation
+
+- **State Handlers:**
+  - `WaitStateHandler` - Idle state with quirk animations
+  - `ReactStateHandler` - User input response with emotion analysis
+  - `TypeStateHandler` - Typing state with emotional variations
+  - `SleepStateHandler` - Inactive state management
+
+- **Animation Loaders:**
+  - `AnimationLoader` - Abstract animation loading interface
+  - `GLTFAnimationLoader` - GLTF/GLB model animation loader
+
+- **Factories:**
+  - `OwenSystemFactory` - Main system assembly factory
+
+### Features
+- **Animation System:**
+  - Support for Loop (L), Quirk (Q), Transition (T), and Nested animations
+  - Automatic metadata parsing from animation names
+  - Efficient animation caching and resource management
+  - Smooth transitions between states and emotions
+
+- **State Machine:**
+  - Four core states: Wait, React, Type, Sleep
+  - Emotional state transitions (Neutral, Angry, Shocked, Happy, Sad)
+  - Automatic inactivity detection and sleep transitions
+  - Message analysis for emotional response determination
+
+- **Developer Experience:**
+  - Comprehensive TypeScript type definitions
