<!-- PR titles must follow Conventional Commits: <type>(<optional-scope>): <description> --> ### Purpose <!-- Linking this pull request to the issue --> Linked issue: close #339 `ArrowUtils::CheckNullabilityMatch` previously validated all physical child values. This incorrectly rejected null values hidden by a null nested parent, although those values are not logically visible. This behavior was also inconsistent with Java. - Track visible ranges while validating STRUCT, LIST, MAP, and VECTOR fields. - Ignore child values masked by a null parent. - Continue rejecting visible nulls in non-nullable fields. - Unify VECTOR element validation with nested nullability validation. <!-- What is the purpose of the change --> ### Tests ArrowUtilsTest, TestCheckNullableMatchParentNullMasksChildren ArrowUtilsTest, TestCheckNullableMatchRejectsVisibleChildNulls <!-- 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 <!-- Does this change introduce a new feature --> ### Generative AI tooling Generated-by: OpenAI 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.
