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.
