CLI App Links

`ed app links`

Lists the external links already shown by Edith.

ed app links [--json]

The fixed ids are repository and creator. Extension lifecycle guides add ids in the form extension-doc:<extension>:<document>, and cached contributors add contributor:<login>. Plain output shows id, label, and URL. JSON is an array whose rows have id, label, and url.

This read needs no running app and does not fetch contributor data. Use an id with ed app open-link.
