K3 (running healthy): running says the health of the build that runs

Browse Source 
The node-engine seat's Running gains healthy, a nullable boolean so that a false survives the wire and a running
said by a node-engine of before G, with none, is told apart and reads as healthy; stopped is said only when the
have no longer holds the module. Two fixtures read healthy true and false; the one without it still decodes.
Generated code waits for K21.

Builds: design 47 G §520
