frank-medium: swap to ParoQuant MXFP6 (Swift Qwen3.8-27B) + Qwen-Sharp v22.5.0

- Model: hugypufy/Swift-Qwen3.8-27B-PARO-MXFP6 (25.16 GiB, 18 shards,
  quant_method=paroquant_mxfp6, bits=6, group_size=128, krot=8, rotation on)
- Image: ggz14/vllm-radiance-mxfp4:0.13.0-e060895 (PR #51 launch6_p kernel,
  built on the published 0.9.3 base; docker->podman via save/load)
- GPU_UTIL 0.98 -> 0.99 (user request); KV_DTYPE=auto (unquantized bf16)
- Entrypoint: mxfp6 branch (17 patches + paroquant kernel compile +
  sitecustomize registration); GPU_UTIL default for set -u robustness
- Quadlet: SNAP/GPU_UTIL/Image/cache updated; new mxfp6 cache dir
- deploy-remote.sh: R4D gate + paroquant_mxfp6; new image/SNAP/cache defaults
- Chat template: Qwen-Sharp v22.5.0 (peculiar-ragdoll); v22.4.0 kept as rollback
- Test 168: dflash branch comment quant-aware (mxfp4 + paroquant_mxfp6)
- Runbook: MXFP6 active shape, MXFP4 rollback

MXFP4 checkpoint remains on disk as the rollback target.
