feat: introduce development mode launch script

- Added a new script (dev.mjs) to start the application in development mode with hot reloading using Vite.
- The script includes functionality for installing Playwright browsers, resolving port configurations, and launching either a web or desktop application.
- Removed the old init.mjs script, which was previously responsible for launching the application.
- Updated package.json to reference the new dev.mjs script for the development command.
- Introduced a shared utilities module (launcher-utils.mjs) for common functionalities used in both development and production scripts.
