Every runtime announces what it serves in the NATS services protocol; the console discovers by asking the bus (hq ADR 0197)

Browse Source 
The Go runtime answers $SRV.PING, $SRV.INFO and $SRV.STATS (and per name and id) in the
io.nats.micro.v1 format with what it serves at the moment it is asked: one service per runtime
process, since the bus admits one reply per request from each responder, and one endpoint per tool
per subject, its metadata saying module, seat, scope, machine, description, schema and whether the
module is interchangeable. Serving is unchanged.

The console gathers one $SRV.INFO request's answers instead of asking the catalogue's roster and
each module's tools, and reads the controller's records as JSON for what should have answered: an
assignment with tools that did not announce is named, a module without tools never is. The text
parsers of node list and module list are gone. Packages share the test bus: go test -p 1.
