Disney+'s <video> is blob-relative (unusable as an absolute clock) and its
scrubber aria-value freezes during playback, so DOM scraping lagged and the
+/-10s button seek could neither reach far targets nor land precisely. The
real player hangs off the <disney-web-player> custom element as
`.mediaPlayer`, exposing seek(ms) and timeline.info (playhead/duration ms).
Since the isolated content world can't read that page object, route it
through the existing MAIN-world page-API bridge (as Netflix already does):
- page-api-seek-overrides.js: register a 'disney' provider.
- background.js installPageApiSeekBridge: seek Disney via mediaPlayer.seek(),
and post the exact playhead/duration (seconds) to the content world every
250ms. Both are gated on provider === 'disney'; Netflix path unchanged.
- content.js: cache the pushed playhead, prefer it in getDisneyPlusTimeline
(DOM scraping stays as fallback), and check the page-API seek first in
seekVideo. Outcome is identical for Netflix and generic sites.
Verified live on Disney+: reported time matches the player exactly and
seek lands within ~1s of the target.
