* fix(runtime): don't restart non-loop media that has naturally ended When a media element's authored data-duration exceeds the actual file length, el.ended becomes true at the file's natural end while the clip is still considered 'active' (timeSeconds < clip.end). The runtime was calling el.play() on the ended element every rAF tick, resetting currentTime to 0 and causing audible stutter for the overshoot duration. Fix: treat el.ended as inactive for non-loop clips. The element sits silently until the composition ends. el.ended resets to false on any seek, so scrubbing backward correctly resumes playback. Reproducer: bg-music WAV is 60s but data-duration='68.6' (composition duration). Last 8.6s: rapid play->clamp->end->play cycle at 60fps. * test(runtime): add seek-recovery contract test for el.ended guard Adds a third test case pinning the seek-recovery property called out in the PR body: a clip that went silent at t=62 (el.ended=true) should resume playing after a backward seek resets el.ended to false.
