feat: enhance native binary resolution and add bundled Node.js runtime

- Refactored gelectron.js to improve native binary discovery with additional paths and environment variable support.
- Implemented a function to find the Node.js runtime, allowing bundled Node.js to be used when available.
- Updated package.json to include gelectron-packager as a CLI command.
- Enhanced gelectron-packager.js to locate installed gelectron runtime and added compatibility for bundled Node.js.
- Modified install-release.sh to download and install a private Node.js runtime alongside the gelectron binary.
- Updated NSIS installer script to include bundled Node.js runtime.
- Enhanced AppImage and DMG packaging scripts to include Node.js runtime.
- Added clipboard, nativeTheme, and screen modules for Electron compatibility.
- Implemented native bridge request handling for clipboard operations.
