`[[VLAN plan]]` only resolves if you remember the exact title or slug, and
nothing in the editor told you either. Typing `[[` now opens a picker at the
caret: filter, pick, and the finished link is written.
It offers documents only. A device with no document is not a link target — a
link at one renders red — and creating a document from inside an unsaved editor
is a different feature; a device that is documented is in the list through its
document, labelled as such.
A target is addressed by title, or as `[[doc:<id>]]` when another document
shares that title. A bare link resolves by title, so an ambiguous one would
silently point at whichever document came first.
The second bracket is swallowed on purpose. Opening the menu moves focus to its
filter field, and a character typed as focus moves is not reliably delivered to
either box, so the body holds exactly one `[` and that is what the insertion
replaces. Cancelling puts the second bracket back, so what was typed survives
whichever way the menu closes.
The popover itself is extracted as EditorMenu and the `/` insert menu now uses
it too — same filter field over a labelled list, placed at the caret and
measured before it is shown, and two copies of that would have drifted.
