The completion-time emptying only takes effect when nothing streamed: the
Desktop keeps already-streamed text when message.complete carries an empty
text (#95514), so a bare NO_REPLY that arrived via message.delta still
rendered in the Bot Chat bubble. Mirror gateway.stream_consumer: for Bot
Chat sessions withhold deltas while the accumulated buffer satisfies
is_partial_silence_marker; flush the held text verbatim once the buffer
diverges from every marker, so a marker never streams and prose that merely
starts like one is delivered intact.
Review finding: streamed NO_REPLY still visible in Desktop Bot Chat because message.delta carried the marker verbatim.
