Use GPU markers when a job needs accelerator hardware.

```yaml
gpu-tests:
  tags:
    - saas-linux-large-amd64
    - gpu:nvidia
    - gpu:count:1
  script:
    - nvidia-smi
    - ./test-gpu.sh
```

## Marker forms

- `gpu:<vendor>`
- `gpu:model:<name>`
- `gpu:count:<n>`

Examples:

```yaml
tags:
  - gpu:nvidia
  - gpu:model:a100
  - gpu:count:2
```

The runner exposes selected GPU information to the job environment.
