> DSv2 Parquet filter pushdown currently runs before Variant extraction
> pushdown. Because of that ordering, filters on variant_get expressions are not
> translated into Parquet filters after the Variant extraction rewrite exposes the
> corresponding shredded fields.
> This change adds a narrow internal pushdown path for rewritten Variant
> predicate filters. V2 scan pushdown translates eligible rewritten filters after
> Variant extraction pushdown, ParquetScanBuilder records the accepted filters,
> and ParquetPartitionReaderFactory passes them to the existing ParquetFilters
> shredded Variant logic when the read schema contains shredded Variant metadata.
> The original Spark filters remain above the scan, so this only improves
> Parquet row-group skipping and does not change query results.
