Add ComfyUI Krea Reference

[kgilper]

Adding my node pack for Krea 2 reference conditioning.

Repo: https://github.com/kgilper/krea-reference

The idea is simple: give each reference image a job before it reaches Krea 2. A guide card assigns each image a plain-language role (keep the same subject, suggest the visual style, copy lighting or pose, big shapes only, avoid copying text/logos), and a stack encoder combines up to 12 cards plus the written prompt into standard conditioning with per-card strength, per-layer gains, and guarded prompt handling.

A few notes for review:

• Pure Python plus a small web extension. No model weights, and no pip dependencies beyond a standard ComfyUI install.
• Registers two nodes under advanced/conditioning: KGKrea2ImageGuideCardV9 and KGTextEncodeKreaImageReferencesV9.
• Ships example workflows, ComfyUI-free contract tests, and full documentation including a technical paper on how the conditioning math works.
• The entry id matches the [tool.comfy] name in the repo's pyproject.toml (comfyui-krea-reference), so a future registry listing maps cleanly.
• JSON validated with a strict parser after the edit (list parses clean, entry count 5181 to 5182).

Thanks for maintaining this. Let me know if anything about the entry needs adjusting.
