Minimax H3 as a single-image edit model

### Feature Idea

It turns out that Minimax can also be a pretty solid Single Image model
using the already existing Singe Image VAE. https://huggingface.co/Mamad8/MiniMax-H3-Image-VAE/tree/main

The problem is that the comfy node does not allow to set the length to t=1 it currently is limited to 5 as minimum.

There are already some code changes being exchanged to get around this this but i feel it would be the best to have real comfy support for this!

Start by locating the ComfyUI node for the Minimax H3 model and the length parameter currently constrained to a minimum of 5. Compare the existing patch in the linked Pastebin and Hugging Face discussion, then verify that setting t=1 supports the single-image VAE workflow without breaking existing multi-image behavior.
