When rapidly interrupting WAAPI animations under CPU load, the element
would jump to incorrect positions. This was caused by using WAAPI's
currentTime for sampling, which doesn't accurately reflect elapsed time
when the main thread is blocked.

The fix uses time.now() from the frameloop to track wall-clock elapsed
time independently, ensuring accurate sampling regardless of main thread
contention.

- Add startedAt timestamp using time.now() in NativeAnimationExtended
- Use elapsed wall-clock time for animation sampling instead of WAAPI currentTime
- Add E2E test reproducing the rapid hover scenario
- Document time.now() usage in CLAUDE.md

Instead of relying on WAAPI's dynamic startTime (which changes on pause/resume),
use a manualStartTime property that gets cleared by play() and time setter,
allowing WAAPI to take over timing when appropriate.

The startTime getter returns manualStartTime when set, falling back to
WAAPI's startTime. Both play() and time setter clear manualStartTime
to allow WAAPI to take over timing.
