Summary

• Preserve stage gate blocks when normalizing workspace workflow YAML into runtime pipeline YAML.
• Parse the final JSON object line from workflow run stdout so noisy scripts can still produce structured gate outputs.
• Add regression coverage for normalized workflow gates and noisy CodeBuild-style stdout.

Why
In prod, the android_validation run command executed and persisted output, but no gate evaluated and the UI stayed silent. The workspace workflow file had a gate, but types.WorkflowStage did not carry gate through normalization, so runtime pipeline YAML dropped it. The same output showed shell trace lines before the JSON status, which made parsed_json become an empty object.
