/**
 * handleContentPermanentDelete must enforce the trash-state contract:
 * permanent deletion is "empty trash", not "skip soft-delete". Calling it
 * on a live (non-trashed) item bypasses the soft-delete safety net and
 * leaves no recovery path, so the handler must refuse the deletion and
 * leave the row intact.
