/**
 * MatchmakerStore（规范 §131）
 *
 * 职责：
 *   - 维护我申请的红娘服务列表
 *   - 维护红娘推荐列表（仅展示，最终 Like/Pass 走 matchStore）
 *   - 维护当前进行中的服务详情
 *
 * 不变量（AGENTS.md）：
 *   - 第 5 条：红娘不可替用户 Like——本 Store 不暴露任何代用户 Like/Pass 的方法，
 *     用户对红娘推荐做出选择时仍走 matchStore.like/pass(userId)。
 *   - 第 7 条：普通工作人员不能查看私人聊天——本 Store 无聊天接入。
 *   - 第 1 条：用户永久免费——红娘服务不引入任何"高级红娘/付费红娘"差异化。
