Implements proper frame timing to prevent frame burst at playback start. Frames are now rendered based on their timestamps relative to playback start time, with late frame dropping to maintain smooth playback. Changes: - Add frame timing system with playback start time tracking - Wrap VideoFrames with timestamp metadata using proper wrapper objects - Use requestAnimationFrame-based scheduling with frame dropping - Add memory leak protection (max 100 timestamp entries) - Standardize worker messages to use consistent object format - Add diagnostic test page to measure frame burst behavior The frame burst test page demonstrates the fix and provides metrics on frame rendering intervals.
