/**
 * @file SCardSet.ts
 * @description 技能卡池独立配置
 *
 * 职责：
 *   维护所有技能卡（CardType.Skill）的原始数据，并构建为标准 CardConfig[]。
 *
 * 设计：
 *   - 技能卡不再按 wave 过滤，所有技能卡均可被抽取。
 *   - 所有技能卡均按次数触发（t_times），不再永久存在。
 *   - card_lv 直接显式配置，不再依赖 wave 推导。
 *
 * 依赖：
 *   - CardSet —— CardConfig / CardType / CKind / CardLV / CardTriggerType
 *   - SkillSet —— SkillOverrides
