/**
 * R-011 API 层集成测试：handleStrategy tabs 域（联动链路）
 * 独立内存 mock settings scope + mock manager，验证：
 *  1. tabs 端点：返回归一化后的统一数组
 *  2. tabs/update：整表更新（顺序 + 显隐）
 *  3. strategies/add：联动追加 tab 条目（末尾）
 *  4. strategies/remove：联动删除 tab 条目 + 清份额（manager）
 *  5. strategies/update：重命名（tabs 行 name join 跟随）
 * 纯内存，不触真实数据（技术约束-011）
