Follows the pack's simple/Advanced batch-loader pattern (multi_image_loader,
multi_audio_loader): drop up to 8 video files onto the node, each gets its
own video_N/audio_N output (plus filename_N on Advanced). video_N is a lazy
VideoFromFile by default (decodes nothing); force_rate > 0 decodes and
retimes frames via resample_frame_indices while keeping real duration.
audio_N is decoded independently with PyAV so it stays available on the
cheap path, and is None (not an error) for clips with no audio track.
Disabled rows hold their socket position, matching the other loaders.
Registered in __init__.py; integration tests follow
tests/test_multi_audio_loader.py's shape (skipped outside a ComfyUI env).
