refactor: Extract Bun functionality into dedicated plugin

- Created tauri-plugin-bun with full Bun runtime integration
- Moved all Bun-related commands from main app to plugin
- Implemented process management with proper lifecycle handling
- Added support for bun install, dev, build, test, and custom scripts
- Created JavaScript API bindings for easy frontend integration
- Removed Bun code from main app lib.rs for cleaner separation
- Updated App.tsx to use new plugin API
- Maintains backward compatibility with existing functionality

This refactor improves modularity and follows the established plugin pattern
used by chrome-manager, podman, and workerd plugins.
