- Correlate by session key first: when both the deferred write and the
confirmation carry a playbackSessionKey, only that is compared, so the
same stream URL played in another playlist no longer records a failed
attempt. URLs remain the fallback (portal writes, MPV/VLC sessions).
The M3U radio player now receives the host's session key.
- Count only playing progress: engines report `playing` (not paused, not
seeking) with each time update, so short seeks of paused media no
longer confirm a view.
- Xtream: a write confirmed after a playlist switch still saves to its own
playlist but no longer replaces the current playlist's recent list.
- Global live tab: a row confirmed after another row was selected still
moves to the top of an open Recently Viewed list (only a disposed tab
skips the notification).
