The `@iptvnator/services` barrel ships in the initial bundle, so adding
PlaybackHistoryGate there (and subscribing to it from the app-wide
ExternalPlaybackService) grew renderer.initialBytes by 1,141 bytes.
- Move the gate to a new lazy-only `playback-data-access` project
(`@iptvnator/playback/data-access`; scope:shared, domain:playback,
type:data-access) and register it in the coverage policy.
- The gate subscribes to MPV/VLC session updates itself; it is created by
the first deferred write, which precedes the launch it waits for.
ExternalPlaybackService is back to master.
- The Xtream "playlist switched before confirmation" check moves to the
lazy helper; the initial-path store only takes a `skipListRefresh` flag.
Net effect on this branch: +27 bytes over master (master itself is
108 bytes over the ratchet baseline already).
