[BUG] If you typo `/exit` as `/ext` you get `/extra-usage`

Preflight Checklist

What's Wrong?

The problem is that it worked. It's easy to make typos. Using Claude Code, you're gonna type the /exit command quite a lot practically for every single Claude session you have. The chances of leaving out a character from it are pretty easy.

In my scenario, I typed /ext by accident, leaving out the "i".

Unfortunately, this acts as the short version of /extra-usage.

Which then goes and harasses my CTO or VP of engineering for more money.

Not a good look for me.

What Should Happen?

Just an error for typing a command that doesn't exist or perhaps assuming I meant exit, as thats the more common case.

Steps to Reproduce

type /ext in claude code.
