go get build-lambda-zip workflow (aws/aws-lambda-go)

The go get build-lambda-zip workflow from aws/aws-lambda-go, explained and optimized by Latchkey.

What it does

This is the go get build-lambda-zip workflow from the aws/aws-lambda-go 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

• Cancel superseded runs when a branch or PR gets a newer push.
• Add a job timeout so a hung step cannot burn hours of runner time.

This workflow runs 1 job (6 with the matrix expanded) per trigger. On Latchkey the same minutes cost up to 58% less than GitHub-hosted, with zero queue time.
