- Add NullBuffer mask parameter to update() - Only count masked-in rows for numRecords - Only count nulls in masked-in rows for nullCount - Filter column by mask before computing min/max - Tests for mask behavior with min/max and null counting This enables deletion vector support where masked-out rows should not contribute to file statistics.
