Update video encodings and native dimensions (1290/1539)

Standard SDR H.264 Main4.0, 8-bit YUV420 / BT.709. Native image dimensions, frame counts and timestamps are retained. Action/state data and existing source qualification annotations are unchanged.

+In progress: 1,290/1,539 videos in this encoding update. See [encoding manifest](meta/video_encoding.json).
 
 Videos use native camera rectangles, including 640 × 480, 1280 × 800 and 848 × 480. Actual per-episode dimensions are listed in [video dimensions](meta/video_dimensions.jsonl). Spatial dimensions are `null` in global feature metadata when episodes have different sizes. The portable loader resolves a selected episode's concrete shapes in memory. For mixed-resolution training batches, configure your model's image preprocessing or group episodes by resolution.
