feat：实现聊天系统核心功能

- 添加 SocketIOClient.gd 实现 Socket.IO 协议封装 - 添加 WebSocketManager.gd 管理连接生命周期和自动重连 - 添加 ChatManager.gd 实现聊天业务逻辑与会话管理 - 支持当前会话缓存（最多 100 条消息） - 支持历史消息按需加载（每次 100 条） - 每次登录/重连自动重置会话缓存 - 客户端频率限制（10 条/分钟） - Token 管理与认证 - 添加 ChatMessage.gd/tscn 消息气泡 UI 组件 - 添加 ChatUI.gd/tscn 聊天界面 - 在 EventNames.gd 添加 7 个聊天事件常量 - 在 AuthManager.gd 添加 game_token 管理方法 - 添加完整的单元测试（128 个测试用例） - test_socketio_client.gd (42 个测试) - test_websocket_manager.gd (38 个测试) - test_chat_manager.gd (48 个测试) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
