> Refactor SQL_COGROUPED_MAP_PANDAS_UDF to be self-contained in read_udfs(),
> moving logic from CogroupPandasUDFSerializer into worker.py, using
> ArrowStreamCoGroupSerializer as pure I/O.
> This follows the same pattern as other eval type refactors in this project
> (e.g., SPARK-55390, SPARK-56123, SPARK-56189, SPARK-56312, SPARK-56477).
