Forge Neo extension brings MiniMax-H3-Image support with golden 8-step CFG=1 recipe

A new Forge Neo extension, pruna-P-H3-Image-forge-neo, adds support for MiniMax-H3-Image and PrunaAI P-H3-Image.

Key settings from the author's testing:

Golden combo: Heun / P-H3-Image scheduler / 8 steps / CFG=1; Euler + Simple + 6 steps gets noisy. The P-H3-Image scheduler is required, and 8 steps beats 6 or 10.
The 32B encoder is unnecessary (and the nvfp4 version doesn't work) — the much smaller INT8-Convrot text encoder gives great results.
Image editing and restoration both work.
Extremely high resolutions run without OOM, but you need to edit ui-config.json to allow width/height above 2048.
