Explanation

A non-zero exit code is the universal mechanism for signaling failure from an action's code. When any step or script exits with a code other than 0, GitHub Actions marks that step-and typically the overall job-as failed. This works across Docker container actions (via CMD or ENTRYPOINT), JavaScript actions (via process.exit(1)), and shell scripts. While the @actions/core toolkit provides setFailed(), it ultimately sets a non-zero exit code under the hood.
