Adapted from HunyuanVideo-FoleyTune for the audio-SR workflow:
- UniverSR Load Video Audio: extract a video's audio track via ffmpeg
(WAV pipe + soundfile, no torchcodec) and carry a UNIVERSR_VIDEO
reference forward, with an inline video preview.
- UniverSR Video Combiner: mux the enhanced audio back onto the source
video without re-encoding video (-c:v copy), trim-aware, with output
auto-increment and preview.
Both registered alongside the SR nodes; ffmpeg + soundfile required only
for these. Adds README docs and an example video workflow.
