* feat(audio): opt-in lazy stream close for bluetooth mic latency
keep the microphone stream open for 30s after recording stops to
reduce latency on back-to-back transcriptions. gated behind an
experimental setting (off by default) since it keeps the mic actively
capturing while idle — degrading bluetooth audio quality on macOS.
adds lazy_stream_close setting, tauri command, toggle in experimental
settings section, and i18n strings.
* fix: gate lazy close on setting in cancel_recording path
cancel_recording was unconditionally calling schedule_lazy_close,
keeping the mic open for 30s even when the setting was disabled.
also bump close_generation on AlwaysOn→OnDemand switch to cancel
any stale lazy close timers.
