Research direction
Start at rust/lance/src/dataset/write/merge_insert.rs around lines 1045-1047 and inspect how subschemas and whenNotMatchedBySourceDelete are currently handled. Trace nearby merge-insert tests or entry points before defining the needed coverage; done means the option works when a subschema is provided.
