* feat(bootstrap): switch GPU injection to CDI where supported
Use an explicit CDI device request (driver="cdi", device_ids=["nvidia.com/gpu=all"])
when the Docker daemon reports CDI spec directories via GET /info (SystemInfo.CDISpecDirs).
This makes device injection declarative and decouples spec generation from consumption.
When the daemon reports no CDI spec directories, fall back to the legacy NVIDIA device
request (driver="nvidia", count=-1) which relies on the NVIDIA Container Runtime hook.
Failure modes for both paths are equivalent: a missing or stale NVIDIA Container Toolkit
installation will cause container start to fail.
CDI spec generation is out of scope for this change; specs are expected to be
pre-generated out-of-band, for example by the NVIDIA Container Toolkit.

* feat(sandbox): add gpu sandbox scheduling support
Allow sandbox creation to request GPU resources explicitly or infer them from GPU image names. This wires GPU intent through bootstrap, validates gateway support, and adds dedicated GPU E2E coverage for follow-up cluster testing.
