Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces support for passing worker binary hashes to the Dataflow runner in the Go SDK. By including the SHA-256 hash in the worker package metadata, the system can better verify worker integrity and ensure consistency during pipeline execution.

Highlights

• Worker Hash Support: Added a new WorkerHash field to JobOptions to track the SHA-256 hash of the worker binary.
• Metadata Integration: Updated the Dataflow runner to include the worker binary's SHA-256 hash in the package metadata during job translation.
• Testing: Added unit tests to verify that the worker package correctly includes the expected SHA-256 hash.

Code Review

This pull request adds support for tracking and verifying the SHA-256 hash of the worker binary in the Dataflow runner. It introduces a WorkerHash field to JobOptions, sets it during execution, includes it in the worker package metadata, and adds unit tests to verify this behavior. The review feedback suggests improving the robustness of the unit test by searching for the "worker" package in the packages list rather than assuming it is the first and only element.
