+`ProjectionBuilder` prunes a DataFusion filter's output for column-only projections, including
+empty projections such as the input to `count(*)`. Each required output column is filtered once,
+then the projection restores its order, duplicates and aliases. The predicate still sees its
+original input schema. Both native plans remain for metrics, including when they share a Spark
+plan ID. Computed projections and projections that use every input column are unchanged.
