   • Updated README.md Contributing Guidelines with linting & test instructions.

3. Packaging & Build Improvements

   • Configured Linux build targets: deb, rpm, pacman (.pkg.tar.zst), AppImage, and tar.gz.
   • Added Windows portable & zip targets and macOS DMG/zip.
   • Updated .github/workflows/build.yml for unified artifact bundling.
   • Added bun.lock to .gitignore.
