/**
 * @file TalentsComp.ts
 * @description 驻场技能信息展示页组件（UI 视图层）
 *
 * 职责：
 *   1. 展示当前所有 FieldSkillSet 配置项的名称、基础值、当前场上总加成。
 *   2. 通过 FieldSkillHelper 实时聚合英雄驻场数据并下发给每个 TalentItemComp。
 *   3. 兼容旧的 `@ecs.register('Talents')` 资源引用。
 *
 * 依赖：
 *   - SkillSet（FieldSkillSet / FieldSkillConfig）—— 驻场技能配置
 *   - FieldSkillHelper —— 场上英雄驻场技能聚合
 *   - TalentItemComp —— 单条驻场技能项视图
