/**
 * Synthesize a Thrift `TGetOperationStatusResp` from the neutral
 * `OperationStatus` DTO. Used by `DBSQLOperation.status()` when running
 * against a non-Thrift backend (e.g. kernel) so the public API stays Thrift-shaped.
 *
 * Carries the rich status fields when the backend supplies them
 * (`numModifiedRows`, `displayMessage`, `diagnosticInfo`, `errorDetailsJson`)
 * — the kernel backend reads these off the terminal kernel statement, so DML
 * operations report `numModifiedRows` at parity with the Thrift path.
 * `numModifiedRows` is re-boxed as a Thrift `Int64` (`node-int64`) to match the
 * wire shape the Thrift deserializer produces, so consumers can read it
 * uniformly across backends.
 *
 * Still lossy for Thrift-only fields not carried by `OperationStatus`
 * (`taskStatus`, `operationStarted`, `operationCompleted`), which are left
 * undefined.
