fix(segments): backport segment-skip fixes from chromecast refactor

Reconcile segment-skip with the diverged-but-ahead version on the
chromecast refactor branch:
- useSegmentSkipper: track auto-skip by segment identity instead of a
  bool, so it no longer re-triggers on pause/unpause; guard skipMode
  "none"; use a finite totalDuration check for Outro.
- Controls: playingRef avoids a stale-closure resume after a seek; only
  resume playback if it was actually playing; skipCredit noop fallback.
- segments: drop the dead try/catch around Promise.allSettled.
- Remove the obsolete useIntroSkipper / useCreditSkipper hooks (177 dead
  lines, superseded by useSegmentSkipper).
