fix: gate publish job on push events only (#8)

The publish job ran on pull_request events because `dry-run` alone
wasn't sufficient — callers that didn't pass `dry-run: true` on PRs
would trigger PR creation from CI. Add `github.event_name == 'push'`
so publish only runs on merges to main regardless of dry-run.
