ComfyUI docs: reflect the running GPU (gfx1151) container

Rewrite ComfyUI.md to match reality: comfyui-rocm:gfx1151 built from
Containerfile.comfyui on AMD's gfx1151 base, device passthrough, video group
only (render is unmappable in rootless), data under /home/dank/comfyui-data,
boot-persistent via a user systemd unit. Mark research 'way 1' as applied and
update the repo-consequence section (the CPU config is no longer the default).

 ComfyUI is a PyTorch app. If you give it a PyTorch wheel with gfx1151 kernels — the AMD `/opt/python` build used by the working vLLM image, or a custom build with `PYTORCH_ROCM_ARCH=gfx1151` — ComfyUI **will** use the GPU via ROCm. The blocker is not ComfyUI; it is shipping it in a container that contains a gfx1151-enabled torch.

 2. **Build PyTorch for gfx1151** (`export PYTORCH_ROCM_ARCH=gfx1151` before build). Slow build, but a self-contained wheel afterwards.
 3. **Use a ggml-family runtime instead** — stable-diffusion.cpp / Lemonade's `sd.cpp` backend ship their own gfx1151 HIP kernels and work today (see [[Lemonade and sd.cpp]]).

 ## Consequence for this repo
 
-The current `dankclaw/compose.yaml` runs ComfyUI with `--cpu`. That remains correct **until a gfx1151-enabled torch image is built**. When GPU priority arrives, swap the image for one based on the AMD Strix-savvy build and drop `--cpu`.
+**Applied 2026-08-19.** `dankclaw/compose.yaml` now builds `comfyui-rocm:gfx1151` from `dankclaw/Containerfile.comfyui` (based on the AMD gfx1151 base), passes `/dev/kfd` + `/dev/dri`, adds the `video` group, and drops `--cpu`. The container runs on the Radeon 8060S (gfx1151) and is boot-persistent via a user systemd unit. See [[ComfyUI]] for the running config.
