CLI App Quit

`ed app quit`

Quits the Edith main window and leaves the menu bar running.

ed app quit [--json]

Name	Type / values	Default	What it does
`--json`	flag	off	Emit JSON on stdout.

--json shape:

{
  "action": "quit",
  "requested": true
}

Examples:

ed app quit
ed app quit --json

Without --json it prints quit requested. This is the one menu-bar-facing verb that is guarded on the main window rather than the helper, because there is nothing to quit otherwise: with the window closed it exits 4 with quit needs the Edith main window to be open, hint open Edith from the menu bar, then retry.

It quits less than the menu bar's own Quit item does. The menu item posts the same request and then terminates the helper as well; ed app quit posts only the request, so the menu bar app survives and ed app open brings the window back.
