Project: Spark
Issue Type: Sub-task
Components: SQL
Affects Versions: 5.0.0

Add Generate-style column pruning to the BinBy logical operator: an
unrequiredChildIndex field plus a requiredChildOutput lazy val (mirroring
Generate), and a ColumnPruning arm for Project over BinBy that trims forwarded
pass-through columns while keeping the range and DISTRIBUTE inputs the kernel
reads. Enabled by the produced-attributes shape from SPARK-57858. Subtask of
