Subject: [PATCH] fix: no text displayed during mic capture

DashScope realtime ASR sends utterance-completed (final) events
without incremental deltas. The onmessage handler cleared
partialTranscript on every final, so text never appeared.

Set partialTranscript to full_text on final messages instead
of clearing it, keeping the transcript visible in QueryInput.
