Initial release: ComfyUI-UniverSR

ComfyUI nodes for UniverSR (ICASSP 2026) — vocoder-free audio
super-resolution (8/12/16/24 kHz → 48 kHz) via flow matching.

- UniverSR Model Loader: presets auto-download to models/universr,
  plus local dir / raw .pth (from_local) loading, with caching.
- UniverSR Super-Resolution: chunked overlap-add for long audio,
  per-channel stereo, seed control with global-RNG isolation,
  wet/dry blend, and an optional before/after spectrogram.
- Vendors the universr inference package under vendor/ (prefers an
  installed copy); only extra dep beyond ComfyUI's stack is torchdiffeq.
