Lint (pre-commit) workflow (corazawaf/coraza)

The Lint (pre-commit) workflow from corazawaf/coraza, explained and optimized by Latchkey.

What it does

This is the Lint (pre-commit) workflow from the corazawaf/coraza repository, a real project running GitHub Actions. It is shown here with attribution under its Apache-2.0 license.

Below, Latchkey shows a faster, safer version produced by its optimization engine.

What changed

• Run on Latchkey managed runners with one line (runs-on), which apply the fixes below automatically and self-heal transient failures. This example uses latchkey-small; pick the runner size that fits the job.
• Add a job timeout so a hung step cannot burn hours of runner time.

This workflow runs 1 job per trigger. On Latchkey the same minutes cost up to 58% less than GitHub-hosted, with zero queue time.
