feat(simulation): wire Sprint 15 systems + protocol v13

Register all new systems in NpcPlugin and SimulationPlugin with correct
ordering constraints. Protocol bumped to v13: tell_state on VisibleEntity,
follow_state and PostConversationQueue on ObserverSnapshot, Follow verb
on VerbKind. Observer snapshot populates tell state from DerivedTellState
and follow state from FollowTarget. System ordering: tolerance after
mood, deviation after activity, tell after mood+deviation, follow after
visibility geometry, event monologue after conversations.
