Summary
This adds scan-based support for
List<Blob>and nested blob leaves such asStruct<List<Blob>>.Descriptor scans preserve the original Arrow nesting and expose blob leaves as descriptors without loading payload bytes.
BlobHandling::AllBinarymaterializes only blob leaves to binary values while keeping the surroundingList/Structlayout intact.This keeps the existing one-blob-per-row APIs unchanged and avoids adding a public random-access API for list blob values.
