> Apply persisted tombstones per field during SCD1 ignore-null reconciliation.
> Before a microbatch is merged, each key's resolved row is dropped if it
> predates the key's tombstone. Today this check is row-wide, but under
> ignore-null, leaf-level reconciliation lets different events author different
> fields of one row, so a tombstone may supersede only some.
