comfyui: replace the stale compose container with a Quadlet unit

ComfyUI had failed 9,146 times and had been down ~7 hours when this was found:
its container was created 2026-09-15 14:12, BEFORE the GPU declarations were
added to the compose service, and `restart: unless-stopped` kept restarting
that stale container — no /dev/kfd, no /dev/dri, no keep-groups — so it died
every time on `RuntimeError: No HIP GPUs are available`. Its "unit" was a
hand-written ~/.config/systemd/user/comfyui.service that shelled out to
`podman compose up -d`, which is not repo-tracked state and collides by name
with the Quadlet the generator produces.

  - dankclaw/comfyui/quadlet/comfyui.container: image comfyui-rocm:gfx1151
    (built from Containerfile.comfyui), /dev/kfd + /dev/dri, keep-groups,
    the four comfyui-data volumes, loopback-only publish (an unguarded service
    is internal-only here; the homepage card probes 127.0.0.1:8188), Restart=
    always, WantedBy=default.target.
  - the compose service is deleted — one owner per container name.
  - deploy_comfyui builds the image, installs the unit, retires the compose-era
    unit into ~/.AGENTTRASH, removes the stale container so the unit's own can
    take the name, and waits on :8188.
  - the healthcheck is a file, because the podman 5.x v1 generator splits
    HealthCmd on spaces and an inline `python3 -c "..."` becomes a quoting
    puzzle that fails silently.

The comfyui seam now reads the unit instead of compose for devices, command and
groups (and resolves the Containerfile from the deployer's declaration, not
from a directory listing).
