👷 Fix alls-green test dependency

[tiangolo]

Summary

• Add the main test job to the alls-green needs list.
• Ensure the required aggregate check sees direct test failures, not only downstream coverage status.

Root cause

The alls-green job did not depend directly on the primary test job, so the JSON passed to re-actors/alls-green omitted that job's status.

Validation

• Parsed .github/workflows/test.yml with PyYAML and asserted the alls-green job needs includes the primary test job.
