Review Comment:
Fixed in 1beb1746c3e4fbef9cb87898dc837d92107b692a. The direct typed fast
path now carries nullable typed_value/wrapper/struct parent null maps down to
copied leaves and ORs them into the leaf null map. This keeps the columnar
direct path for present rows while rows with an absent typed struct materialize
as root Variant null. Added
ParquetVariantReaderTest.DirectTypedOnlyPreservesNullableTypedStructNull. Local
verification: ./run-be-ut.sh --run --filter="ParquetVariantReaderTest.*";
./build.sh --be; ./run-regression-test.sh --run --conf
tmp/regression-conf.auto.groovy -d external_table_p0/tvf -s
test_local_tvf_iceberg_variant; build-support/check-format.sh; git diff --check.
