Summary
Pin all third-party GitHub Actions to full-length commit SHAs to prevent supply chain attacks.
Addresses findings from the

Note
Low Risk
Low risk: this only pins external GitHub Actions to specific commit SHAs; the main risk is CI behavior changing if the pinned revisions differ from the previously floating tags.
Overview
Pins third-party GitHub Actions to immutable commit SHAs for supply-chain hardening.
