Add narrative event types (task_started, npc_slept, npc_died, resource_depleted) alongside economic transfers. EconomicEventRecord gains create_narrative factory and human-readable description method. SimulationManager records task-start and sleep/death events, exposes get_npc_events() for per-NPC history queries. Inspector now shows a Recent timeline of the last 5 events for the selected NPC, plus displays carried wood count. Relax EconomicEventRecord validation to accept non-economic events. Update roadmap with completed milestones.
