Christian PillsburyandClaude Opus 4.8 6125c93216 refactor(spf): gate track reload on completeness, not a serviced-epoch counter
Replace the resolve-track loader's fused reload gate (`isResolvedTrack(track)
&& epoch <= lastLoadedEpoch`) and its `let lastLoadedEpoch` closure-local with
a pure `shouldResolveTrack` predicate keyed off `Track.duration` completeness:
unresolved → load, resolved-but-incomplete → reload, resolved + complete →
reuse. A switch to a resolved-but-incomplete live track now eagerly re-fetches
(its window may have slid past the playhead), which is what makes the
last-serviced memory unnecessary — every effect re-fire is a legitimate load,
with in-flight dedup and the peeked presentation preventing redundancy.

The reload-epoch slot becomes purely a re-fire ping: subscribed to, never
compared. Completeness via `Number.isFinite(track.duration)` is the existing
single source of truth, so a live stream that hits ENDLIST stops reloading with
no engine- or stream-type config.
