Without this attribute the player-ready poll burned the full 45 s timeout
on every render (CSS-only comp never registers window.__timelines[id]).
Both baseline and fast dropped from ~50 s to ~7 s; fast-capture speedup
now measures 1.34× (was 1.04× — 45 s init overhead on both paths masked
the actual drawElement gain).

* fix(core): drive adapter seeks when composition has no GSAP timeline
renderSeek returned early when deps.getTimeline() was null, skipping the
onDeterministicSeek call that drives all frame adapters (CSS, WAAPI,
Lottie, Three.js). That meant compositions using any non-GSAP animation
primitive froze on their initial frame during capture.
Now we still quantize the seek time and fire onDeterministicSeek even
without a timeline, so each adapter gets a chance to advance.
GSAP compositions are unaffected — timeline-driven seek still takes the
same path it did before.
