refactor: remove architecture documentation and improve code readability

- Deleted ARCHITECTURE.md file to streamline project documentation.
- Refactored AudioEngine, EventTarget, MediaBunnyEngine, VideoEngine, VideoShim, and index.js for improved readability by adding consistent line breaks and spacing.
- Enhanced code structure by ensuring single-responsibility principles and clearer flow in methods.
- Updated TypeScript definitions for better clarity on options available in the artplayer-proxy-mediabunny package.
