CLI App Clean Keys

`ed app clean-keys`

Locks the keyboard so you can wipe it without typing into whatever is in front.

ed app clean-keys [--json]

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

--json shape:

{
  "action": "clean-keys",
  "requested": true
}

Examples:

ed app clean-keys
ed app clean-keys --json

Without --json it prints clean-keys requested. This is the menu bar's keyboard-cleaning lock, so it needs the helper and exits 4 with clean-keys needs the Edith menu bar app to be running when the helper is closed. The request is fire and forget: ed posts the notification and returns, so exit 0 means the request was sent, not that the lock came up.

What the helper does with it is the same path the System page's button takes. It re-reads its permissions, ignores the request outright when a clean is already under way, and if Input Monitoring or Accessibility is missing it raises that request instead of locking; otherwise it dismisses the panel, arms the countdown and shows the overlays. If the System extension is off the helper has no system store at all and the notification lands nowhere, and ed still exits 0, so check ed extensions ls for system when nothing happens.
