Initial release: ComfyUI nodes for STAR video super-resolution

Two-node package wrapping the STAR (ICCV 2025) diffusion-based video
upscaling pipeline:

- STAR Model Loader: loads UNet+ControlNet, OpenCLIP text encoder, and
  temporal VAE with auto-download from HuggingFace
- STAR Video Super-Resolution: runs the full diffusion pipeline with
  configurable upscale factor, guidance, solver mode, chunking, and
  color correction

Includes three VRAM offload modes (disabled/model/aggressive) to
support GPUs from 12GB to 40GB+.
