Enable sound when Gemini is "done"

[LycalopX]

Many times when using the Gemini CLI, I like to sit around and let it do boring tasks that require no monitoring, such as commenting large ammounts of code, or finding a fix for a bug, however, I can never tell when it is done. It would be pretty good if there were a shortcut for enabling a ring for when it is "done" with a task, i.e., expeting another response from the user.
