refactor(ai): E001 贯彻"AI只决策"——每状态=一能力(Model A)

AI 决策层(E001CaoZhiAi + PerceptionStateMachine)彻底移除所有 actuation：
不再有 Mover.Stop/FacePlayer/UseChaseSpeed/WalkRandom、也不再 SetPhase。
每个 AI 状态只声明触发哪个能力 id，行为(移动/朝向/停/速度/动画/伤害/
阶段声明)全部下沉到对应能力里。

- 新增 IdleAbility/PatrolAbility/AlertAbility：待机静止、巡逻游走、
  警觉朝向玩家，各自 SetAiPhase 驱动阶段动画。
- ContactChaseAbility 追击进入时自设 RunSpeed + Chase 阶段(原在 AI)。
- PerceptionStateMachine 改为 AddAbilityState：进入/每帧 EnsureAbility
  (被打断/受击后自动重触发)、离开 InterruptAbilities；转换规则不变。
- IEnemyActor/EnemyBrainContext 移除已无用的 SetPhase，保留 HasAlertState。
- 新增 SO：ABL_E001_Idle(e001_idle)、ABL_E001_Patrol(e001_patrol)。
- 脚手架 PlaceE001 与 ENM_CaoZhi 预制体同步为四能力结构；TestRoomA
  实例替换为规范预制体实例。

PlayMode 验证：Chase→ContactChaseAbility、脱离感知→Move_Patrol→
PatrolAbility，阶段由能力设置，无报错。
