Description
GitHub Actions can now run steps in parallel via parallel step groups (or background: true + wait-all): https://github.blog/changelog/2026-06-25-actions-steps-can-now-be-run-in-parallel/
Independent, network-bound setup steps (repository checkouts, artifact downloads, toolchain setup) can overlap instead of running serially.
