App-only explicit promotion for an already-inserted opener/outro object. Reads the addressed Program occurrence, promotes its preset params and gain to the project Brand Studio default opener/outro slot or to that role's alternates through the same identity_apply_to_project path, writes a promotion receipt, and affects future reels only. It does not mutate this or any other composition, and it never changes the pack enabled state.
