[BUG] Cannot type "n" key in /config language field (Windows/Git Bash)

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?

In the /config command UI, the "n" key cannot be typed in the language field.

When trying to type language names like "Japanese", "Indonesian", or "Norwegian",
the "n" character does not appear when pressed. All other keys work normally.

The only workaround is to copy-paste the text from an external editor like Notepad.

What Should Happen?

The "n" key should insert the "n" character into the language field,
allowing users to type language names containing "n" (e.g., Japanese, Indonesian, Norwegian).

Steps to Reproduce

1. Open Claude Code in Git Bash (MINGW64) on Windows
2. Run /config command
3. Navigate to the "language" field (text input field)
4. Try to type the letter "n"
5. Observe that no character appears

Note: Other configuration fields use Enter/Space selection and work fine.
Only the language field uses keyboard text input, and only the "n" key is affected.
