Event Producer And Consumer Matrix

This matrix shows which packages dispatch each harness-owned event and which packages listen to it. Events are many-to-many, so the dense relation data is presented as a table rather than one large graph. Receiver and event-name types also cover contained dispatch sites that deliberately bypass ctx.emit, such as subagent lifecycle containment.
