stt.finish() used to run inline in the frame loop, deafening the
assistant for up to ~4s per utterance while the server returned the
transcript (and whatever was said meanwhile was later drained). The
finish now runs on a background thread per utterance; the segmenter
keeps consuming mic frames, so speech during the wait becomes its own
utterance and is transcribed too. Transcripts are delivered oldest-
first between frames, deferred while an utterance is in progress, and
the command/follow-up window no longer times out on transcription
latency. Speaking stays half-duplex (echo protection).
