// Background alternative to ExecuteChangeRequest.cs (tracker §37) — for a large batch (e.g. a
// full base-schema baseline, proven live in §36.13 to run for several minutes), queues the CR for
// ChangeRequestExecutionWorkerJob's own Quartz timer instead of running inline on this HTTP
// request's own CancellationToken, which an ordinary client-side timeout would otherwise abort
// mid-batch with no way to resume. ExecuteChangeRequest.cs itself is untouched — still the right
// call for small/interactive CRs that finish in well under a request timeout.
