refactor: remove dev.mjs and integrate start-automaker.sh for development mode

- Deleted the dev.mjs script, consolidating development mode functionality into start-automaker.sh.
- Updated package.json to use start-automaker.sh for the "dev" script and added a "start" script for production mode.
- Enhanced start-automaker.sh with production build capabilities and improved argument parsing for better user experience.
- Removed launcher-utils.mjs as its functionality has been integrated into start-automaker.sh.
