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.

-## 🎮 Animation Naming Convention
+## 🎨 Multi-Scheme Animation Naming
+
+Owen supports **four different animation naming schemes** to accommodate different workflows and preferences:
+
+### Naming Schemes
+
+| Scheme           | Format                       | Example                     | Use Case                        |
+| ---------------- | ---------------------------- | --------------------------- | ------------------------------- |
+| **Legacy**       | `{state}_{emotion}_{type}`   | `wait_idle_L`               | Backward compatibility          |
+| **Artist**       | `Owen_{Action}`              | `Owen_WaitIdle`             | Blender-friendly for 3D artists |
+| **Hierarchical** | `owen.{category}.{state}...` | `owen.state.wait.idle.loop` | Structured projects             |
+| **Semantic**     | `Owen{StateAction}{Type}`    | `OwenWaitIdleLoop`          | Developer-friendly              |
+
+### Usage Examples
+
+```javascript
+// All of these refer to the same animation:
+const clip1 = owenSystem.getClip('wait_idle_L');                    // Legacy
+const clip2 = owenSystem.getClip('Owen_WaitIdle');                  // Artist  
+const clip3 = owenSystem.getClip('owen.state.wait.idle.loop');      // Hierarchical
+const clip4 = owenSystem.getClip('OwenWaitIdleLoop');               // Semantic
+
+// Convert between schemes
+import { convertAnimationName, SemanticAnimations } from 'owen';
+
+const artistName = convertAnimationName('wait_idle_L', 'artist');
+// Returns: 'Owen_WaitIdle'
+
+// Use type-safe constants
+const animation = SemanticAnimations.WAIT_IDLE_LOOP; // 'OwenWaitIdleLoop'
+```
+
+### For 3D Artists (Blender Workflow)
+
+```javascript
+// Use artist-friendly names in Blender:
+// Owen_WaitIdle, Owen_ReactHappy, Owen_TypeFast, etc.
+// System automatically handles conversion!
+
+const clip = owenSystem.getClip('Owen_ReactAngry');  // Just works!
+```

+
+## 🎮 Animation Naming Convention (Legacy)
+
+The system maintains backward compatibility with the original naming convention:
 
 The system expects animations to follow this naming convention:
