More reliable speaker separation on busy Macs

AirNote now monitors memory pressure while it separates speakers during a session. If your Mac becomes too busy, AirNote safely pauses that local processing and keeps the recorded audio ready to continue, rather than forcing the speaker model to run under pressure.

When the session ends, AirNote waits briefly for capacity to return and retries from the saved audio. This helps AirNote process sessions more reliably on older Macs with less available memory. The transcript and Note screens explain the delay, and if speaker separation still cannot finish safely, AirNote preserves a usable transcript without speaker labels so the session is not lost.
