Subject: [PATCH] ci: add permissions block and update actions/checkout to v4

- 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.
