The `kilo github install` command hides the GitHub Copilot provider without any explanation when users cancel or don't select a provider, leaving them unaware of this option.

Add a helpful note that appears when:

1. User cancels the provider selection (presses Ctrl+C)
2. User doesn't select a valid provider from the list
   The message should inform users about GitHub Copilot availability and provide a link to setup documentation.
