Gate pass 5 flagged test_gpu_detection.py:31 in test_file_spot: the
`ROLE / "vars" / "main.yml"` chain hard-codes a role-file path the
utils.roles.mapping SPOT already names.

Follow-up to ae259a9f58 after an independent review:
- The 136-character task name broke the 80-character name lint
(tests/lint/repository/test_name_emoji_and_length.py). Names are short
again; the device/driver/host matrix lives in the role README.
- Both stats now always run and lookup('gpu') requires both registers,
instead of reading a skipped device stat as "no device".
- A bare host that shows /dev/nvidia0 without nvidia-smi stops the
deploy with a message naming the fix. It used to die on the missing
binary anyway; ae259a9f58 would have run its GPU services on the CPU
silently. A container in that state (a swarm lab node, the dev
container without its GPU override) still runs on the CPU.
- svc-ai-s1 decided its CUDA build from its own stat of /dev/nvidia0 and
nvidia-container-runtime while its runtime came from lookup('gpu'), so
a host with the toolkit but no nvidia-smi would have built a CUDA image
that gets no GPU. S1_GPU now reads lookup('gpu'), the one detection.
- The libretranslate-engine README and the s1 TODO describe the new
detection.
test_gpu_detection walks the real tasks over device, driver and
container; against the original 00_core.yml it fails in the
driverless-container, driverless-bare and device-and-driver cells.

The local 061 Nextcloud swarm step failed on every lab node in
"Ask the driver which CUDA devices this host carries" with
"[Errno 2] No such file or directory: b'nvidia-smi'". The lab nodes are
privileged containers (compose/swarm/compose.yml), so on a workstation
with an NVIDIA card they see the host's /dev/nvidia0, but they carry no
driver. The device node alone made them GPU hosts, for the GPU include
and for lookup('gpu') alike, which would also have picked a -cuda image
and runtime: nvidia for a GPU service there.
The role now stats SYS_SVC_CONTAINER_GPU_DRIVER (/usr/bin/nvidia-smi)
first and stats the device node only where the driver exists; the
skipped register reads as "no device" in lookup('gpu'), and the include
requires a device stat that ran and found the node. The query runs the
same binary the detection probed. Hosts with driver and device (bare
metal with the driver, the compose dev container through the GPU
override) and hosts without a device (CI) behave as before.
test_gpu_detection walks the real tasks over the four driver/device
cells and fails on the old 00_core.yml in exactly the device-without-
driver cell.
