fix: skip formatter check for Java projects

- Add Java case in _detect_formatter() that returns empty list
- Change default formatter-cmds to empty list instead of black
- This fixes "Could not find formatter: black" error for Java projects

Java formatter support is not implemented yet, so we skip the check
entirely for Java projects.
