- Copy complete source code packages from original CodeNomad project
- Add root package.json with npm workspace configuration
- Include electron-app, server, ui, tauri-app, and opencode-config packages
- Fix Launch-Windows.bat and Launch-Dev-Windows.bat to work with correct npm scripts
- Fix Launch-Unix.sh to work with correct npm scripts
- Launchers now correctly call npm run dev:electron which launches Electron app
