Review Comment:
Updated. The BLOB field indices are now cached in `RowType` itself via a
`transient volatile` lazy field, following the same pattern as the existing
`laziedNameToField` cache. This gives the cache the same lifecycle as the
`RowType` and removes the global weak-key cache in the Spark module.
Semantics are unchanged, and the returned set is unmodifiable.
