/**
 * @file EquipSet.ts
 * @description 装备卡池独立配置
 *
 * 职责：
 *   定义所有装备卡的静态数据，与技能卡池（CardSet.CardPoolList）彻底分离。
 *   装备卡不再参与抽卡，改为商店直购，任务开始时一次性全部展示。
 *
 * 装备生效机制：
 *   购买 → 派发 GameEvent.UseEquipCard → MissEquipComp 接收 → EBox ECS 实体
 *   → EquipBoxComp（trigger_type=Field，被动驻场）→ FieldSkillHelper 全局聚合属性加成
 *
 * 依赖：
 *   - CardConfig / CardTriggerType / CardType / CKind（CardSet）
 *   - FieldSkillSet（SkillSet）—— 属性词条配置
