All conflicted hunks resolved in favour of antalya-26.6 ("ours"): the
source PR's changes are already present on the base branch in an evolved
form (upstream ClickHouse#101272 plus its 26.6 follow-ups), so no source-PR line is
lost:
* ArrowColumnToCHColumn.cpp: `unwrapNullableTuple` list/Nested handling and
the null-value zeroing in `readColumnWithNumericData` are already on
antalya-26.6; kept the base branch's extra last-offset validation and the
`schema_inference_allow_nullable_tuple_type`-gated STRUCT condition
(backport of ClickHouse#109185), which supersedes the PR's unconditional removal of
the STRUCT check.
* CHColumnToArrowColumn.cpp: struct-level null handling already exists on
antalya-26.6 via `nullBytemapToArrowBitmap` + `arrow::StructArray::Make`
(the builder-based Append/AppendNull shape from the PR no longer applies).
* MsgPackRowInputFormat.cpp: identical Nullable(Tuple) unwrapping already on
antalya-26.6, only placed after the tuple size check.
* 04064/04065 tests: base-branch versions already cover the PR's cases;
04065 was adapted on antalya-26.6 to the V3-reader-only world where
`input_format_parquet_use_native_reader_v3` no longer exists.
Also dropped the cherry-pick's misplaced copy of the "zero out values at
null positions" block: git applied it to `readColumnWithDurationData`,
a function the source PR does not touch, while the PR's actual target
(`readColumnWithNumericData`) already carries it on antalya-26.6.
