Add better auth as a auth option as it is superior to Auth.js in terms of flexibility and option offerings: https://www.better-auth.com/

Make it so the user can use the CLI, select better auth, and the DB, then it automatically populates the app with the proper database configuration and betterauth configuration for the basic username and password as well as oauth which the user can use to extend using betterauth's plugins.
