> SPARK-56677 supports merging subqueries when a filter comes from one join
> child. When filters come from both children, PlanMerger currently skips the
> merge.

> Combine the two propagated filters with AND above the join so the subqueries
> can share one join execution. Keep existing join safety checks unchanged.
