[BUG] Typing an "n" in the input of "new permission" dialog exits it

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [x] This is a single bug report (please file separate reports for different bugs)
• [x] I am using the latest version of Claude Code

What's Wrong?

1. I run /permissions
2. Press twice the right arrow to select "Deny"
3. Press <kbd>Enter</kbd> to "Add a new rule..."
4. Start typing Bash(ansible-playbook:*) but just as I type the n letter, it exits the dialog. Typing n right away has the same effect

What Should Happen?

It should let me enter the command without exiting the dialog unless I press <kbd>Esc</kbd>.
