A module emits and consumes events, both declared (emits/consumes),
parallel to provides/requires. Events are 1:many, broadcast, credential-
free — no provisioner, just the broker's topic routing — so most inter-
module reaction should be an event, not a provision. Every event carries
source/node/time so it is auditable; the audit logger is just a module
consuming '#', no privilege. A consumes for an event nothing emits is a
dangling edge and refused, like requires. One per-node runtime serves
tools, provisioning and events alike.
Extends ADR 0045; builds on ADR 0001 (the broker) and 0044 (emit/on are
stable sdk surface; the binding and runtime are not).
