fix: use PAT token to allow workflows to trigger on PR merges (#8)

GitHub's GITHUB_TOKEN doesn't trigger workflows to prevent infinite loops.
Using PAT (with fallback to GITHUB_TOKEN) allows release workflow to trigger
when PRs are merged to main.

To enable: Add PAT to repo secrets as 'PAT' with 'repo' and 'workflow' scopes.
