Npcs/TaskBase.cs
An abstract base class for NPC tasks used by a scheduling system. It stores a reference to the parent Schedule and its Npc, tracks task Status, and exposes lifecycle methods that call protected virtual/abstract hooks: OnStart, OnUpdate, OnEnd, and Reset. Public lifecycle is driven via internal Initialize, InternalUpdate, and InternalEnd.
