- Add `permissions: contents: read` at workflow level to follow least-privilege principle - Update `actions/checkout` from v2 to v4 (v2 is deprecated) This reduces the default GITHUB_TOKEN scope and uses the current checkout action version.

Summary
permissions: contents: readat the workflow levelactions/checkoutfrom v2 to v4Why
Least-privilege GITHUB_TOKEN: Without an explicit
permissionsblock, workflows run with the default token permissions, which include write access to repository contents, packages, and other resources. Addingcontents: readrestricts the token to read-only access, reducing the blast radius if a dependency or action is compromised.Deprecated action version:
actions/checkout@v2is deprecated and no longer receives updates. v4 includes security fixes and performance improvements.Files (1)
