Research direction

Examine the existing GitHub Actions workflows in the repository (e.g., .github/workflows/). Understand how Zizmor is configured and run locally. Determine which workflows need to be updated to add Zizmor checks. For the immutable releases and sigstore signing, note that those require maintainer permissions and are separate from code changes.
