Subject: [PATCH] Pin GitHub Actions to SHA for security
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Update official GitHub Actions (actions/*, github/*) to use pinned
commit SHAs instead of version tags. This satisfies zizmor's
unpinned-action-reference security check.
