`Scripts.toml` + GitHub Actions workflow that uses cargo-run as the single
entry point. The workflow:
1. 2.3.
```bash
cd examples/ci-cd
cargo script ci # local dry-run
cargo script ci --json # machine-readable output
cargo script ci --dry-run # see what would run
```
Want a different CI provider? Use a template:
```bash
cargo script init --template gitlab-ci
```
