ss14-npc-system-core

Deep dive into the NPC system in SS14/Sunrise: HTN planning, utility target selection, steering/pathfinding, blackboard and execution contracts. Use it when you need to understand the general scheme and logic of NPCs, create or rework behavior prototypes (`htnCompound`, `rootTask`, `blackboard`), or write your own AI code (operators, preconditions, components, systems) and safely integrate it into runtime.
