Purpose
Implements the blob-view-field feature, which allows a downstream table to store lightweight references (
BlobViewStruct) pointing to blob data in upstream tables. At read time, these references are resolved back intoBlobDescriptors by scanning the upstream table, enabling cross-table blob sharing without duplicating data.Tests
