feat: 扩展 Session Manager 接口，新增 ListByUser、UpdateTitle 方法

Browse Source 
- Manager.Create 签名新增 userID 参数
- 新增 ConversationSummary 类型和 ListByUser 分页查询
- 新增 UpdateTitle 方法
- MemoryManager 实现：ListByUser 遍历+过滤+排序，UpdateTitle，自动标题生成
- RedisManager 实现：user:{id}:sessions 索引，ListByUser 通过 SMEMBERS 查询
- AppendMessage 自动更新标题（首条 user 消息时，取前 20 字符）
- 更新 ws handler、api/session.go、orchestrator mock 的 Create 调用
