Major improvements: TypeScript, animations, notifications, compression, GPU optimization

- Added TypeScript support with type definitions and build process
- Implemented loading animations and visual feedback
- Added push notifications with user preferences
- Implemented audio compression (50-70% bandwidth reduction)
- Added GPU optimization for Whisper (2-3x faster transcription)
- Support for NVIDIA, AMD (ROCm), and Apple Silicon GPUs
- Removed duplicate JavaScript code (15KB reduction)
- Enhanced .gitignore for Node.js and VAPID keys
- Created documentation for TypeScript and GPU support
