// sub_conn_thread.h
// Linux/macOS 客户端子连接 worker 线程的统一骨架。
//
// 各 worker 线程Shell / ScreenSpy / FileManager / SystemManager 等)共有的步骤:
// 1. new IOCPClient(g_bExit, exit_while_disconnect=true)
// 2. Enter log
// 3. EnableSubConnAuth(true, g_myClientID)(子连接强制 ConnAuth
// 4. ConnectServer内部会执行 PerformConnAuth失败返 false
// 5. 创建 platform handler
// 6. setManagerCallBack 装回调
// 7. 调 onReady发首包TOKEN_TERMINAL_START / SendBitmapInfo() 等)
// 8. while (running && connected && !g_bExit) Sleep
// 9. 清回调防止 dangling
// 10. Leave log
// 11. catch exceptions
//
// 平台差异(通过 lambda 注入):
// - HandlerTPTYHandler / ScreenHandler / SystemManager / FileManager
// - createHandler 可返回 nullptr 表示初始化失败(如 macOS ScreenHandler 无录屏权限)
// - onReady 完成首包发送或额外 setup
//
// 用法见 linux/main.cpp / macos/main.mm 的 *workingThread 调用点。
