### Purpose `LanceRowTypeVisitor.visit(ArrayType)` returned without checking the element type, so `MULTISET` / `MAP` / `LOCAL_ZONED_TIMESTAMP` passed `validateDataFields` when nested in an `ARRAY`, even though the visitor rejects them at the top level and recurses through `ROW`. `ARRAY<MULTISET<...>>` then failed at write time in `ArrowFieldTypeConversion.visit(MultisetType)` instead of at `CREATE TABLE`. Recurse into the element type, same as `VortexFileFormat` (#8690) and `MosaicFileFormat`. ### Tests `LanceFileFormatTest` — added a rejecting case for `ARRAY<MULTISET<STRING>>` and kept `ARRAY<ARRAY<INT>>` passing. 7/7 pass; both fail without the fix. -- This is an automated message from the Apache Git Service.
