Review Comment:
   This regression only scans the files through `local(...)`, so it bypasses 
the actual Iceberg table path changed by this PR. In particular, it does not 
exercise FE `SlotTypeReplacer.replaceIcebergAccessPathToId()` converting access 
paths to Iceberg field IDs, nor BE `IcebergParquetReader::_create_column_ids()` 
calling the Iceberg field-id pruning helper. A bug in field-id access-path 
serialization or Iceberg-specific column-id selection can therefore pass this 
suite while failing `SELECT v['...'] FROM iceberg_tbl`. Please add an 
end-to-end Iceberg external table regression (with nested VARIANT access and 
profile/read-column assertions where possible) that reads these VARIANT files 
through the Iceberg catalog/table path rather than only through local TVF.
