ChatController:
- final/aborted/error run events now trigger a history refresh regardless of
whether the runId is in pendingRuns; only delta events require the run to be
tracked (prevents voice-initiated responses from being silently dropped)
MicCaptureManager:
- Don't auto-send on onResults silence detection — accumulate transcript
segments and send when mic is toggled off, giving the recognizer time to
finish processing buffered audio
- Capture any partial live transcript if no final segments arrived (2s drain
window before stop)
- Join multi-segment transcripts with sentence-ending punctuation to avoid
run-on text sent to the gateway
