What's Wrong?

When setting the value for a plugin's userConfig, typing the n character auto closes the configuration wizard and does not save the value, i.e. typing out the path /Users/nathan closes the wizard when the first n is typed.

Copy and pasting the full value (even if it contains the n character) seems to work fine.

What Should Happen?

The plugin configuration input should not close automatically when the n character is typed. The user should be able to complete their userConfig key input without having the wizard closed if the value they are inputting contains an n character.

Additional Information

For the userConfig property for plugins, the documentation is missing the type and title values. Installing the plugin without these values for a config item throws errors for the plugin. See documentation here: https://code.claude.com/docs/en/plugins-reference#user-configuration
