* fix(runtime): clear play guard after hard seek to prevent audio desync on scrub When scrubbing the timeline during playback, syncRuntimeMedia detects the offset jump and hard-seeks the media element. But the in-flight play() guard (playRequested WeakSet) from the previous play() call prevented the next sync tick from re-issuing play() — leaving the element paused at the new position for 50-150ms while the GSAP timeline continued advancing. This caused audible audio desync after every scrub. Fix: clear playRequested on the element after a hard seek so the very next sync tick can re-issue play(). Also adds a lint rule (video_audio_double_source) that catches compositions where an unmuted <video> and a separate <audio> point to the same source — a pattern that causes double playback at runtime.

Seeking past the buffered range silently fails — currentTime stays at 0 while the timeline advances, causing permanent audio desync that only a page refresh fixes. Three changes: 1. Move preload="auto" enforcement to run for ALL active elements on every sync tick (not just during play). This catches elements whose preload was overridden after init.ts set it. 2. After a hard seek, check if currentTime actually reached the target. If not (drift > 0.5s), call load() once to force the browser to fully fetch the media and build a complete seek index. 3. Clear the load-retry guard when the clip leaves its active window so re-entry can retry if needed. Reproduced on hyperframes.dev Hermes launch video: vo.mp3 buffered to 15.96s, seeking to 20s failed silently. bg-music.wav (fully buffered) was unaffected.
