test: add deterministic test case for specific version matching

- Add test that matches exact release version (2.11.1) by title pattern
- This provides a deterministic test case that verifies exact behavior
- Fix error handling to ensure proper error message when no releases match
- All 4 gh-title-pattern tests now pass
