Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — The PR is limited to ignored dependency manifests and checksum updates, with no direct source-code or schema changes. Because it changes production dependency versions specifically to remediate grpc CVEs, the security-sensitive dependency selection should receive human review.

Not approved because:
