CancellationTargetOperationId is the id of the movement a Núclea-coordinated CANCELLATION targets (E-5.3). Populated ONLY on the CANCELLATION path (null for every other type), so a consumer can correlate a cancellation to the operation it cancels. Mirrors the optional SettlementIfISPB projection (nullable, always present).
Recoverability diagnostics: the operator distinguishes an external wait (waitingFor set → use reconcile) from an internal block (waitingFor nil + stuckSince set → use advance/requeue); lastError carries the most recent recorded Núclea error.
