Clean & Format JavaScript

How it works
- Use Remove debug preset to strip logs and debugger before committing code.
- Use Production ready to remove all comments, logs, alerts, and TODOs.
- Beautify uses js-beautify — safely handles template literals and regex.
- console.log and all console.* are mutually exclusive — pick one.
- Comment removal is regex-based — avoid running on already-minified input.
