docs: update completion status for Phases A-D.3

Mark all resource system phases (A, B, C, D.1-D.3) as complete in
the LLM integration roadmap and design docs. D.4 (structure
inspection) remains as future work.

 ### 2.2 Resource, Tool & Invention System (Phased)
 
 **Phase A — Harvestable Map + Gathering:**
-- [ ] Map generation: water ponds, stone deposits, tree clusters as resource tiles
-- [ ] ItemRegistry singleton with seed resources (log, stone, water)
-- [ ] NPC inventory component + inventory helpers
-- [ ] Productivity need (decays like hunger/energy, motivates gathering)
-- [ ] npcBrain: 'gather' goal when productivity low
-- [ ] gatheringSystem: walk to resource tile → timer → add to inventory
