CNN v2 test tool: Add video playback support
Features:
- Video file support (MP4, WebM, etc.) via drag-and-drop
- Play/Pause button with non-realtime playback (drops frames if CNN slow)
- Frame-by-frame navigation (◄/► step buttons)
- Unified image/video processing through same CNN pipeline
- Audio muted (video frames only)
Optimizations:
- Layer visualization updates only on pause/seek (~5-10ms saved per frame)
Architecture:
- copyExternalImageToTexture() works with both ImageBitmap and HTMLVideoElement
- Video loading: wait for metadata → seek to frame 0 → wait for readyState≥2 (decoded)
- Playback loop: requestAnimationFrame with isProcessing guard prevents overlapping inference
- Controls always visible, disabled for images
