- A pinned playground model that is unavailable now errors clearly instead of
silently answering from the managed local model (route_source no longer lies).
- The managed CMF model is surfaced in GET /admin/api/models (marked "managed",
shown read-only in the UI) so the real running model is visible and pinnable
without a hand-maintained [[models]] entry; a fresh install still lists nothing.
- Deleting a model now removes its local .cmf physically (file or tensor-dir);
deleting the managed model also stops the server and clears the [cmf] config.
Routing is stripped of the deleted id so the config still validates.
