race condition debug wip

Also trigger poll_daily_room_presence_task when user joins meeting via

polls needed for both join and leave events.

+Hatchet child workflow: TrackProcessing
+
+Handles individual audio track processing: padding and transcription.
+Spawned dynamically by the main diarization pipeline for each track.
+
+Architecture note: This is a separate workflow (not inline tasks in DailyMultitrackPipeline)
+because Hatchet workflow DAGs are defined statically, but the number of tracks varies
+at runtime. Child workflow spawning via `aio_run()` + `asyncio.gather()` is the
+standard pattern for dynamic fan-out. See `process_tracks` in daily_multitrack_pipeline.py.
+
+Note: This file uses deferred imports (inside tasks) intentionally.
+Hatchet workers run in forked processes; fresh imports per task ensure
+storage/DB connections are not shared across forks.
