> Refactor SQL_COGROUPED_MAP_ARROW_UDF to be self-contained in read_udfs(), moving logic from CogroupArrowUDFSerializer into worker.py, using ArrowStreamSerializer 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).
