/**
 * 优化后的Zulip服务 - 实现游戏内实时聊天 + Zulip异步同步
 * 
 * 核心优化：
 * 1. 🚀 游戏内实时广播：后端直接广播给同区域用户，无需等待Zulip
 * 2. 🔄 Zulip异步同步：使用HTTPS将消息同步到Zulip作为存储
 * 3. ⚡ 性能提升：聊天延迟从 ~200ms 降低到 ~20ms
 * 4. 🛡️ 容错性强：Zulip异常不影响游戏聊天体验
 * 
 * 职责分离：
 * - 业务协调：整合会话管理、消息过滤等子服务
 * - 流程控制：管理玩家登录登出的完整业务流程
 * - 实时广播：游戏内消息的即时分发
 * - 异步同步：Zulip消息的后台存储
 * 
 * 主要方法：
 * - handlePlayerLogin(): 处理玩家登录和Zulip客户端初始化
 * - handlePlayerLogout(): 处理玩家登出和资源清理
 * - sendChatMessage(): 优化的聊天消息发送（实时+异步）
 * - updatePlayerPosition(): 更新玩家位置信息
 * 
 * 使用场景：
 * - WebSocket网关调用处理消息路由
 * - 会话管理和状态维护
 * - 游戏内实时聊天广播
 * - Zulip消息异步存储
 * 
 * 最近修改：
 * - 2026-01-10: 重构优化 - 实现游戏内实时聊天+Zulip异步同步架构 (修改者: moyin)
