§7, §428 (watchman): a bus user is said by its module's name, the tool runner's no differently

signals.go BusUserWords: the node-tools special word is gone (the node-engine's node.<node> user stays, a bus account form, not a
module name). The watchman's ControlNodeModule (signals.go:591, nats) and builderModule (names.go:17) went with A-197 and WM13.

Builds: design 47 G §7, §428
