Research direction

Start by tracing DataFusion's existing array_intersect or list-intersection implementation and the SQL expression parser, using the DuckDB nested-functions reference linked in the issue for expected behavior. The work is done when && accepts two list values as an alias for array_intersect and tests cover the example [1,2,3] && [4,5].
