Christian PillsburyandClaude Opus 4.8 57a426db6b docs(spf): explain why syncLiveSeekableRange doesn't clear on termination ...

Reframe the "clearLiveSeekableRange() on termination" follow-up as a
deliberate non-action rather than a gap. Per the W3C MSE spec, the live
seekable range is consulted only while duration === Infinity; when a live
stream ends, endOfStream() sets a finite duration and the UA derives seekable
from buffered + duration, ignoring the live range — so clearing is unnecessary.
Clearing on the ENDLIST->finite-Track.duration transition would also be
premature (duration is still Infinity until endOfStream) and shrink seekable to
buffered-only. No logic change; the existing behavior (bail on null window) is
already correct, and the 'no-ops for a complete playlist' test locks it.
