- Updated RowNumber, RowNumberDesc, RowNumberPartionBy, and RowNumberDescPartionBy to accept variadic extraOrderBy parameters
- Fixed bug in RowNumberDesc that was incorrectly using ASC instead of DESC
- Enhanced rowNumber internal function to build ORDER BY clause with primary field and additional fields
- Backwards compatible - existing code continues to work without extra fields
- Added CLAUDE.md documentation for future Claude Code instances
