feat: structured narrative event feed with per-NPC inspector timeline

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.

 The practical next sequence is:
 
-1. Continue growing resource discovery with finite `ResourceNode` instances
-   placed in meaningful foliage, animal-camp, berry, and village-stockpile
-   contexts. The first distance/safety/comfort scoring pass, twelve authored
-   resources, and placement validation exist; next additions should increase
-   authored variety only when they preserve reachability, stable IDs, scoring
-   metadata, and clear player interaction ranges.
-2. Expand persistence only when schedules, player state, or a real save menu

+1. Expand the structured event feed with actor/target/cause metadata so the
+   inspector can show a readable timeline per NPC. Narrative events for task
+   starts, sleep, and death are recorded; next should add depletion notices,
+   relationship seeds, and village-level event summaries filtered by relevance.
+2. Seed relationship dimensions (familiarity, trust, obligation) from shared
+   work, meal, and sleep proximity, then expose them through utility
+   considerations so NPCs begin to prefer known colleagues and familiar routes.
+   Start with one lightweight dimension before building the full graph.

+- Resource discovery expanded to 18 finite ResourceNodes across farming,
+  deep-forest, river-bank, and mill-adjacent contexts with scored metadata.
+- NPC schedules implemented: SLEEP/MEAL/WORK/DISCRETIONARY periods driven by
+  simulation clock time-of-day. DayNightCycle synced to simulation clock. NPCs
+  walk home to designated house positions at night, sleep to restore energy,
+  eat at meal times, and work during the day. Starving NPCs always override
+  sleep to seek food.
+- Starvation balance reworked: hunger ~25/day, death threshold ~3 days of
+  starvation (realistic ~6-7 day survival without food). Energy drain uses
+  exact binary fractions for lossless JSON serialization.
+- Wood inventory and woodpile storage: wood now follows the same
+  gather→carry→deposit pattern as food. VillageWoodpile StorageNode receives
+  wood deposits. Village wood syncs from storage. Economic events track all
+  transfers.
+- Structured event feed: EconomicEventRecord now supports narrative events
+  (task started, NPC slept, NPC died) alongside economic transfers.
+  Per-NPC event history with human-readable descriptions exposed in the
