chore: pin GitHub Actions workflows (#35)

Pinning GitHub Actions to full commit SHAs reduces supply-chain risk and makes workflow runs reproducible even when floating tags move. This PR updates every workflow action to an exact SHA, keeps the corresponding released version visible inline, removes package-manager caching from the release workflow, and aligns CI with the same Node.js LTS version used for release and website jobs.
