A route's internal name says where the request arrives

novox/hq ADR 0151 (issues 139, 157). <label>.<node>.internal is answered
by every resolver as 'anything under that node goes to that node', so
the node in a route's internal name must be the one whose proxy answers
it; composed under the consumer's own name it sent a client to a machine
with nothing listening whenever the proxy ran elsewhere. Composed under
the serving node now — the same machine wherever the proxy runs beside
the module, so nothing changes on a mesh with one hub.

A routed public name gets no .internal alias any more: the roster
publishes it as itself, once. The alias resolved and nothing served it.
