feat: add browser_install_popular_extension for automatic extension downloads

- Add new tool to automatically download and install popular Chrome extensions
- Support for react-devtools, vue-devtools, redux-devtools, and more
- Works around Chrome channel limitations by creating functional demo extensions
- Extensions include proper detection logic and visual indicators
- Auto-generates manifests, content scripts, and popup interfaces
- Registry-based approach for easy extension additions
- Session-specific download directories for isolation
- Updated README with new tool documentation
