Subject: [PATCH] :recycle: Rename app.graph.overlay to
 app.graph.relation-overlay
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The holder vocabulary names a graph by scope and a holder by
location, scope, and form, so the overlay namespace takes the
holder's name: app.graph.relation-overlay, with its console,
queries, and sync children. Aliases keep their short forms.

schema-version keeps its "penpot-graph-overlay-2" literal: it is
a storage version, and renaming it would rekey stored artefacts
without a schema change.
