refactor(skill): 重构技能触发逻辑，提取统一工具类
将分散在Hero、Mon、HeroAtkSystem、SCastSystem、MissionComp中的技能触发代码统一封装，集中处理触发次数加成、实体合法性校验与技能事件派发，同时新增SkillTriggerType枚举统一管理技能触发类型，简化业务调用并消除重复模板代码。

/**

* 特殊触发技能的统一中介者 (Mediator)
|

*
|

* 核心职责：
|
||||
* 1. 统一管理英雄/怪物的各类生命周期触发技能（召唤、死亡、战前、战后、攻受击）。
|
||||
* 2. 集中处理触发次数的计算（如：局内羁绊加成、局外天赋加成）。
|
||||
* 3. 作为唯一出口，通过事件总线向 SCastSystem 派发 GameEvent.TriggerSkill 事件。
|
||||
*
|
||||
* 优势：
|
||||
* - 极大地解耦了具体业务组件（Hero/Mon/HeroAtkSystem/MissionComp）与技能系统。
|
||||
* - 避免了原先散落在各处的判定逻辑和冗余的事件派发代码。
