The node's runtime is its modules' bus: it binds each module's consumer and hands its events to the bundle (hq ADR 0198)

A launched bundle's mesh/subscribe binds the module's own durable consumer — EVENTS, <node>_<module>,
by name as the module's own runtime bound it, so nothing is lost or replayed in the move — and every
event goes to each child of the module that subscribed as mesh/event, acknowledged only when all
answered, negatively acknowledged after a short delay when one failed or died, terminated when it is
not an event. mesh/ask calls a tool as the module. Every launched bundle is started again when it
exits, with backoff, since long-running code waits for no call. Requires SDK 0.1.6.
