Subject: [PATCH] feat: use dedicated auto-merge action for reliability

Changes:
- Replace gh pr merge with peter-evans/enable-pull-request-automerge action
- Add pr_number output to create_pr step
- Support auto-merge for both new and existing PRs
- Simplify workflow by removing manual merge logic
- Better error handling and reliability

Benefits:
- More robust auto-merge using GraphQL API
- Works even if repository allows auto-merge is disabled
- Clearer separation of concerns
- Better support for existing PRs
