Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — The change adds an external account to the repository's trusted contributor allowlist, enabling that account's PRs to pass the gate for signed macOS preview builds using release credentials. Because this broadens a CI authorization boundary, it requires human review.
