ThomasEricB/minimax-h3-pinokio ? reverse-engineered prompt

Build me a one click launcher for MiniMax H3 inside ComfyUI so a normal person can install it, start it, and use it without wiring anything up.

I want the app to clone ComfyUI, install the right Python and CUDA setup, download all the needed H3 model files, and add ready to run workflows for text to video, image to video, and reference to video. When it finishes, the menu should make it easy to start ComfyUI and open the web UI, and there should be a simple way to reinstall the bundled workflows if they get changed.

Please make it work for NVIDIA GPUs on Linux or Windows, use the newer CUDA 13 torch stack so the quantized models run properly, and include the option to install the faster SageAttention 3 path for RTX 50 series cards if it helps. Keep the prompts and workflow defaults set up so users can just pick a workflow, type a prompt, and generate video with audio right away.
