Pin external third-party actions to full-length commit SHAs with a trailing version comment to mitigate mutable-tag supply-chain attacks. Internal SecureAuthCorp/* references intentionally left on floating tags. No functional change: each SHA resolves to the commit the existing tag points to. DEVOPS-8397

Approve: pin external GitHub Actions to commit SHAs (DEVOPS-8397). Verified each pinned SHA matches its version tag; no functional change.

Summary
Pin every external third-party GitHub Action to a full-length commit SHA with a
trailing version comment, mitigating the mutable-tag supply-chain attack class
(e.g. the
tj-actions/changed-filescompromise). A moved tag can no longer swapcode into our CI — the SHA is immutable, and the comment preserves the original
version for readability and Renovate updates.
Internal
SecureAuthCorp/*references are intentionally left on floating tags(
@main/@v1) — same-org sources where floating is by design and theexternal-maintainer threat does not apply.
No functional change: every SHA resolves to the exact commit the existing tag
currently points to.
