feat(blueprint): 添加蓝图触发器系统 (#323)

* feat(blueprint): 添加蓝图触发器系统

- TriggerTypes: 定义触发器类型和上下文接口
  - tick/input/collision/message/timer/stateEnter/stateExit/custom
  - 各类型的上下文接口和工厂函数

- TriggerCondition: 触发条件系统
  - ITriggerCondition 接口
  - 复合条件 (CompositeCondition, NotCondition)
  - 通用条件 (AlwaysTrue, AlwaysFalse, TriggerType, EntityId)
  - 特定类型条件 (InputAction, MessageName, StateName, TimerId, CollisionEntity, CustomEvent)
  - ConditionBuilder 链式 API

- BlueprintTrigger: 触发器核心实现
  - IBlueprintTrigger 接口
  - BlueprintTrigger 实现类
  - TriggerRegistry 触发器注册表
  - 各类型触发器工厂函数

- TriggerDispatcher: 触发器调度系统
  - ITriggerDispatcher 调度器接口
  - TriggerDispatcher 实现
  - EntityTriggerManager 实体触发器管理器

* feat(blueprint): 添加触发器相关事件节点

- EventInput: 输入事件节点 (action/value/pressed/released)
- EventCollisionEnter/Exit: 碰撞事件节点
- EventMessage: 消息事件节点
- EventTimer: 定时器事件节点
- EventStateEnter/Exit: 状态机事件节点
