Release QA — active transcript reconciles on session events
Fixed
- An open WebUI transcript now reconciles when another client/process updates it (#4208). The #3916 external-refresh guard correctly skips WebUI-native sessions on the 30s poll, but also left the open transcript stale on real
sessions_changedevents. The poll-skip is now scoped to the periodic poll path only; event/focus/visibility triggers run the divergence check (guarded against refresh loops) and reconcile the active transcript, not just the sidebar.
