fix(ci): make release workflow run on PRs as dry-run

- Add pull_request trigger to satisfy branch protection
- Actual release creation only happens on push to main
- PR mode passes check without creating release
- Fixes chicken-and-egg: PR can't merge because Release required,
  but Release only runs after merge
