Event Producer And Consumer Matrix

This matrix shows which packages dispatch each harness-owned event and which packages listen to it. It is intentionally a table rather than one large graph: events are many-to-many, and dense relation data is easier to review in rows. Receiver and event-name types also cover contained dispatch sites that deliberately bypass ctx.emit, such as subagent lifecycle containment.
