zebra-spaces: one transcript line per sentence (host self-transcribe parity)

Browse source 
Fox 2026-06-05: "the self speech to text is not creating new lines
for when there is new sentence, the listeners are doing a better
job."

Both self-capture and remote-speaker capture go through the same
handleWhisperChunk → appendTranscriptLine path. Each Whisper chunk
is 5 seconds. The listener-side capture often catches a peer mid-
pause, so each 5s chunk ends up holding one short sentence — one
line in the log. The host on a close mic talks continuously for
the full 5s window, so Whisper returns "Hello there. How are you.
Good to see you." as a single string → one mashed line.

Fix at the dispatch point (not the capture point): split the
Whisper output on sentence-terminating punctuation
(period/exclaim/question followed by whitespace) and call
appendTranscriptLine once per sentence. Each sentence gets the
same hallucination + min-length filtering as the original whole
result.

Applies to BOTH self capture and remote capture since they share
the same handler — listener-side transcripts also get cleaner when
two sentences happen to fit in one chunk.
