<!-- PR titles must follow Conventional Commits: <type>(<optional-scope>): <description> --> ### Purpose <!-- Linking this pull request to the issue --> Linked issue: #197 Backport Arrow community fixes for nullable `FixedSizeList` Parquet read/write: - Writer: support child values split by null list slots. - Reader: pad null slots before constructing `FixedSizeListArray`. - Remove Paimon's Parquet-specific VECTOR write conversion and write through Arrow directly. The backport follows Arrow's current implementation, with only a C++17 `arrow::util::span` adaptation for Arrow 17. Related: apache/arrow#35692, apache/arrow#35697, apache/arrow#50271. <!-- What is the purpose of the change --> ### Tests - Nullable and all-null FixedSizeList round trips. - Nullable Java LIST and Rust FixedSizeList fixtures. - Mixed Java/Rust file reads. - Nested VECTOR and predicate pushdown. <!-- List UT and IT cases to verify this change --> ### API and Format <!-- Does this change affect API in include dir or storage format or protocol --> ### Documentation Updated the VECTOR compatibility fixture documentation. <!-- Does this change introduce a new feature --> ### Generative AI tooling Generated-by: Codex (GPT-5) <!-- If generative AI tooling has been used in the process of authoring this patch, please include the phrase: 'Generated-by: ' followed by the name of the tool and its version.
