👀 Reviewer Notes

This workflow is designed to safely automate syncing of forks without affecting contributors' work. Forks with diverging commits are skipped intentionally to avoid conflicts or data loss. Some forks may not sync due to GitHub permission limitations

This is an important enhancement because it helps keep forks automatically up to date with the upstream repository, reducing manual effort for contributors. The workflow safely syncs only non-diverging forks and improves overall project maintainability.
