kevinveenbirkenbachandClaude Opus 5.5 137afc60cc fix(sys-svc-container): require device and driver for a GPU host, refuse a driverless bare host
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.
