After a metadata state machine commit, the Reply message had an empty body -- mux_stm.update() returned () and the result was discarded. Clients need the response (e.g. assigned IDs) to proceed without a second query. StateHandler::apply now returns Bytes, stored in a last_result field on each *Inner struct during left_right::Absorb (which forces () return). After publish(), the result is read back through ReadHandle and propagated through State -> StateMachine -> MuxSTM into build_reply_message, which now accepts a body parameter and constructs a variable-length BytesMut buffer instead of a header-only transmute. All 19 handlers return Bytes::new() for now.
