feat(qwen-image-bench): replace qwen3.6-35b-a3b on GPU1 with the T2I judge (NVFP4)
flukethoughts/Qwen-Image-Bench-NVFP4 — Qwen's text-to-image quality JUDGE (vision-intact, NVFP4) on ana-ml2 GPU 1, replacing qwen3.6-35b-a3b: - stacks/qwen-image-bench/ — vLLM multimodal serve (Qwen3_5ForConditionalGeneration, no text-only patch — vision wanted), GPU1 device pin, :8014. util 0.32 (0.22 KV-starved → crash-loop "no available memory for cache blocks"; util is a fraction of TOTAL so it must clear the ~20GB weight floor). - litellm: removed qwen3.6-35b-a3b + -thinking; added qwen-image-bench + qwen-image-judge alias. Verified live: healthy (KV 9.4GB / 133K tokens), text + IMAGE (vision path) both respond. NOTE: arbo's hero-judge was bound to qwen3.6-35b-a3b — comfy-dev notified to repoint.
