Menu item for global hotkeys/quick terminal

[HamishWHC]

Currently, I need to ensure I leave Ghostty running in the background in order to keep my global quick terminal hotkey working. I tend to use cmd+q to quit all my terminal windows at once, and I'd prefer to have quit-after-last-window-closed = true to keep my dock clean when I don't have a terminal open. It would be nice if global hotkeys/quick terminal were handled by a menu item that persists after the main Ghostty process is quit, so that I cannot accidentally lose quick terminal access.

There was another discussion suggesting this. If I find it I will close this. My question is: how do you do this from a macOS perspective? I'm happy to do it but haven't yet found the mechanism.
