## 问题
生产环境收到 WebSocket 消息但不触发通知：
- Network 面板显示消息已接收
- 但事件监听器未触发（事件处理函数不执行）
- 手动测试 `window.__TEST_NOTIFICATION__.testAllTypes()` 正常工作
- 诊断脚本显示 `window.socket: undefined`

## 根本原因
Socket 实例未暴露到全局作用域，导致：
1. 无法验证 NotificationContext 中的监听器是否注册在正确的 Socket 实例上
2. 可能存在多个 Socket 实例（导入的实例 vs 实际连接的实例）
3. 事件监听器注册在错误的实例上

## 解决方案
在 `src/services/socket/index.js` 中暴露 Socket 实例到 window 对象：

### 代码变更
```javascript
// ⚡ 新增：暴露 Socket 实例到 window（用于调试和验证）
if (typeof window !== 'undefined') {
    window.socket = socketService;
    window.socketService = socketService;

    console.log('✅ Socket instance exposed to window');
    console.log('  📍 window.socket:', window.socket);
    console.log('  📍 Socket.IO instance:', window.socket?.socket);
    console.log('  📍 Connection status:', window.socket?.connected);
}
```

## 好处
1. **可调试性**: 可在浏览器 Console 直接访问 Socket 实例
2. **验证监听器**: 可检查 `window.socket.socket._callbacks` 确认监听器已注册
3. **诊断连接**: 可实时查看 `window.socket.connected` 状态
4. **手动测试**: 可通过 `window.socket.emit()` 手动触发事件

## 验证步骤
部署后在浏览器 Console 执行：
```javascript
// 1. 验证 Socket 实例已暴露
console.log(window.socket);

// 2. 检查连接状态
console.log('Connected:', window.socket.connected);

// 3. 检查监听器
console.log('Listeners:', window.socket.socket._callbacks);

// 4. 测试手动触发事件
window.socket.socket.emit('new_event', { id: 999, title: 'Test' });
```

## 影响范围
- 修改文件: `src/services/socket/index.js`（1 个文件）
- 影响范围: 仅新增调试功能，不改变业务逻辑
- 风险等级: 低（只读暴露，不修改 Socket 行为）
