Note

Low Risk
Small CI-only change that updates a third-party GitHub Action version; minimal blast radius but could affect release automation if the new action behavior differs.

Overview
Updates the Release GitHub Actions workflow to use cycjimmy/semantic-release-action@v5 (from @v4) for the Semantic Release step, aligning the release pipeline with newer action/runtime support.
