Parse a DO response as a RunSummary, translating a non-ok answer into a
RunRouteError carrying the DO's own status, message and reason. A 5xx
without a reason code is a fault the DO did not classify: its message is
logged and the error carries internal error. A non-ok answer whose body is
not JSON keeps its status.
