A process answers its seat's verbs through one call: caller-named and
unproven subjects, one queue group per seat, reply {result, error, node}.
The rule that a process answers no call (issue 1171 AC3) is replaced by one
that AnswerSeat is the only way to serve. A compare-and-set write on a
process's own state already exists (State.Create, Update).

The lease write asked seat:node-service-manager.stop@novox-be through Conn.Call, which published
the '@' inside the subject: nobody served it and the call timed out after 30 s with nothing said
(issue 774 notes 84-87). Every key now parses in one place, calladdress: Call routes '@node' as
CallOn does, and stdio Ask refuses a key the runtime could not route, before anything is sent.
