// Note: Detection relies on matching a substring from the backend's IllegalStateException
// message ("Cannot transition a queue entry that has already ended") because the REST
// response does not include a structured error code for this case — unlike duplicate
// entry errors which use a bracketed code. If the backend message changes, this will
// silently fall through to the generic error handler, which is an acceptable degradation.
