fix(simulation): wire triangle crisis event queue into observer snapshot

The TriangleCrisisEventQueue was populated by tick_triangle_escalation
but never drained into ObserverSnapshot — clients always saw an empty
vec despite protocol v16 advertising the field. Now drains the queue
each tick and converts to TriangleCrisisEventWire.
