feat: Implement WebGPU context manager and shaders for ocean rendering

- Added WebGPUContext class to manage WebGPU initialization and resource creation.
- Created main_webgl.ts for WebGL rendering setup and scene management.
- Introduced WGSL shaders for Perlin noise generation and ocean rendering.
- Implemented vertex and fragment shaders for ocean surface displacement and lighting effects.
- Enhanced camera controls and rendering logic for improved user experience.

+# WebGPU Migration Complete
+
+## Overview
+Successfully migrated the WebOcean project from WebGL2 to WebGPU to enable future tessellation support for the ocean grid system.
+
+## What Changed
+
+### Files Converted to WebGPU:
+
+1. **Grid.ts**
+   - Replaced WebGL VAO/VBO with GPUBuffer
+   - Updated `initVAO()` → `initBuffers(gpuContext: WebGPUContext)`
+   - Changed `draw(gl: WebGL2RenderingContext)` → `draw(renderPass: GPURenderPassEncoder)`
+   - Uses `mappedAtCreation` pattern for buffer initialization
+
+2. **Skybox.ts**
+   - Same conversion pattern as Grid
+   - Replaced WebGL buffers with GPUBuffer
+   - Updated draw method signature for WebGPU
+
+3. **main.ts** (renamed from main_webgpu.ts)
+   - Replaced `initGL()` with async `initWebGPU()`
+   - Created three render pipelines:
+     * Noise generation pipeline (renders Perlin noise to texture)
+     * Ocean rendering pipeline (vertex displacement from noise texture)
+     * Skybox pipeline (gradient sky with sun)
+   - Converted FBO to GPUTexture for render-to-texture
+   - Updated all shader bindings to use WebGPU bind groups
+   - Maintains all existing features:
+     * Dual camera system (Orbital + FPS)
+     * Animation controls (P pause, 0-5 speed)
+     * Wireframe toggle (F key)
+     * Camera switching (C key)
+     * Full WASD + mouse controls
+
+### New Files Created:
+
+1. **WebGPUContext.ts**
+   - Centralized GPU device/adapter/context management
+   - Provides helper methods for creating buffers, textures, pipelines
+   - Handles WebGPU initialization and configuration
+
+2. **shaders.wgsl.ts**
+   - All GLSL shaders converted to WGSL format
+   - Exports 6 shader strings:
+     * `noiseVertexShader` - fullscreen quad for noise generation
+     * `noiseFragmentShader` - 5-octave Perlin noise
+     * `oceanVertexShader` - vertex displacement from texture
+     * `oceanFragmentShader` - normal calculation, Fresnel, SSS, glitter
+     * `skyboxVertexShader` - skybox cube rendering
+     * `skyboxFragmentShader` - gradient sky with sun
+
+### Preserved Files:
+
+1. **main_webgl.ts** (backup)
+   - Original WebGL2 implementation preserved for reference
+   - Excluded from TypeScript compilation
+
+### Configuration Updates:
+
+1. **tsconfig.json**
+   - Added `"types": ["@webgpu/types"]` for WebGPU type definitions
+   - Excluded `main_webgl.ts` from compilation
+
+2. **package.json**
+   - Added `@webgpu/types` dev dependency
+
+3. **index.html**
+   - Added frame time display (`<div id="frame-time">`)
+   - Kept GLSL shader script tags (not used, can be removed later)
+
+## WebGPU vs WebGL2 Architecture
+
+### Key Differences:
+
+| Aspect | WebGL2 | WebGPU |
+|--------|--------|--------|
+| **Buffers** | VAO/VBO with gl.createVertexArray() | GPUBuffer with device.createBuffer() |
+| **Shaders** | GLSL with gl.createProgram() | WGSL with device.createShaderModule() |
+| **Rendering** | Direct gl.drawArrays() calls | Command encoder → render pass → submit |
+| **Textures** | gl.createTexture() + gl.texImage2D() | device.createTexture() |
+| **State** | Implicit state machine (gl.enable/disable) | Explicit pipeline state in descriptors |
+| **Uniforms** | gl.uniformMatrix4fv() per draw | Uniform buffers + bind groups |
+
+### Rendering Pipeline:
+
+**Pass 1: Noise Generation**
+```
+1. Write time uniform to buffer
+2. Create command encoder
+3. Begin render pass with noiseTexture as target
+4. Set noise pipeline
+5. Set noise bind group (contains time uniform)
+6. Draw fullscreen quad (6 vertices)
+7. End pass and submit commands
+```
+
+**Pass 2: Scene Rendering**
+```
+1. Update camera uniforms (view, model, projection, eyePos)
+2. Update skybox uniforms (view, projection, sunDir)
+3. Create command encoder
+4. Begin render pass with canvas + depth texture
+5. Draw skybox:
+   - Set skybox pipeline (no depth write, no culling)
+   - Set skybox bind group
+   - Draw skybox geometry
+6. Draw ocean:
+   - Set ocean pipeline (depth write, back-face culling)
+   - Set ocean bind group (contains uniforms + noise texture + sampler)
+   - Draw ocean grid (wireframe or solid)
+7. End pass and submit commands
+```
+
+## Browser Compatibility
+
+- **Requires**: Chrome/Edge 113+, Firefox 130+ (with flag)
+- **Not supported**: Safari (as of December 2024)
+- Shows error alert if WebGPU not available
+
+## Testing Checklist
+
+✅ Build succeeds without TypeScript errors
+✅ Dev server starts successfully
+✅ WebGPU initialization completes
+✅ Dual camera system functional
+✅ Animation controls work (pause/play/speed)
+✅ Wireframe toggle functional
+✅ Mouse camera controls responsive
+✅ Keyboard FPS camera controls work
+
+## Next Steps - Tessellation
+
+Now that WebGPU migration is complete, tessellation can be implemented:
+
+1. **Hull Shader** - Define tessellation factors based on camera distance
+2. **Domain Shader** - Interpolate tessellated vertices
+3. **Dynamic LOD** - Increase subdivision near camera, reduce far away
+4. **Adaptive Tessellation** - More detail in areas with high wave displacement
+
+This will provide:
+- Smoother ocean surface at all zoom levels
+- Better performance (fewer vertices far from camera)
+- More geometric detail for displacement mapping
+- Hardware-accelerated mesh subdivision
+
+## Files Modified Summary
+
+- ✅ [Grid.ts](Grid.ts) - WebGPU buffer conversion
+- ✅ [Skybox.ts](Skybox.ts) - WebGPU buffer conversion
+- ✅ [main.ts](main.ts) - Complete WebGPU rendering pipeline
+- ✅ [WebGPUContext.ts](WebGPUContext.ts) - New GPU management class
+- ✅ [shaders.wgsl.ts](shaders.wgsl.ts) - New WGSL shader definitions
+- ✅ [tsconfig.json](../tsconfig.json) - Added WebGPU types
+- ✅ [index.html](../index.html) - Added frame time display
+- 📦 main_webgl.ts - Backup (excluded from build)
+
+## Performance Notes
+
+- FPS display shows frame rate
+- Frame time display shows milliseconds per frame
+- Animation speed control (1x-5x)
+- Pause/play functionality preserved
+- WebGPU generally faster than WebGL2 for complex scenes
