Build me a simple cross platform command line tool that helps people fix common Cursor setup problems on Windows, macOS, and Linux.

I want it to check where Cursor is installed, back up any local settings first, then make the needed local changes automatically so the app can be opened again without the usual trial or suspicious activity warning getting in the way. It should be easy to run from Terminal or PowerShell, and it should guide the user with clear messages if it can’t find Cursor.

Please make it work as a one command experience for each operating system, with a safe confirmation step before changing anything important. If you need to look up current install paths or shell details online, go ahead and do that.
