feat: update to burn 0.14.0 with vulkan support and refactor frontend to egui

- Updated burn framework dependencies from 0.21.0-pre.2 to 0.14.0
- Added optional vulkan backend support with burn-wgpu feature
- Replaced React/TypeScript frontend with native Rust egui frontend
- Added Vulkan GPU support documentation and setup instructions
- Updated README with new architecture and backend configuration
- Refactored GPU backend detection and reporting to include backend type
- Added vulkan-backend feature flag for conditional compilation
- Updated dependency installation instructions for Vulkan support
