🐛Android端VPN模式会导致QQ连接超时

### 🐛 描述(Description)

安卓端使用VPN模式加速会导致QQ/TIM连接超时，而使用仅代理模式没有加速效果

### 📷 复现步骤(Steps to Reproduce)

1. 打开启用VPN模式
2. 点击加速
3. 进入TIM
4. 出现连接超时提醒

### 📄 [异常/日志]信息([Exception/Log] Information)

### 🚑 基本信息(Basic Information)

- 程序版本(Program Version):2.7.2 α for Android (arm64)
- 系统版本号(OS Version): HarmonyOS 2.0.0.230(C00E230R7P5patch01)
- 是否为应用商店版本(Whether it is a Store version): 否

Start by reproducing the timeout on Android or HarmonyOS with VPN mode enabled, then compare the same acceleration flow in proxy-only mode. Trace the Android VPN and acceleration entry points responsible for QQ/TIM traffic; done means QQ/TIM connects successfully while VPN-mode acceleration remains enabled.
