修复：onlyTransfer 模式下断网弹出两个网络断开提示框

问题

UOS 向 Windows 投送文件过程中断开 UOS 端网络，Win 端的 dde-cooperation-transfer 弹出两个网络断开提示框，期望只弹一个。必现。

根因

dde-cooperation-transfer 在 Win 端同时加载 cooperation-core 和 data-transfer/core 两个插件，各自启动独立的 1 秒网络监控定时器，均轮询 getFirstIp().size() > 0。断网时两个定时器先后发射 onlineStateChanged(false)，分别驱动协同窗口（mainwindow.cpp）和迁移窗口（mainwindow_p_win.cpp）切换到网络断开页面，用户看到两个提示框。

根因点在 CooperaionCorePlugin::start() 中无条件调用 mainWindow()->show() 和 MainController::instance()->start()，未检查 onlyTransfer 属性。

修复方案

在 CooperaionCorePlugin::start() 中增加 onlyTransfer 检查：

• 当 onlyTransfer=true 时，跳过 mainWindow()->show()（不显示协同窗口）和 MainController::instance()->start()（不启动协同模块网络监控定时器）
• 保留基础服务（regist()、配置、翻译）
• 从源头消除重复网络监控，仅保留数据迁移侧的单监控器

改动

• src/plugins/cooperation/core/cooperationcoreplugin.cpp：start() 函数增加 onlyTransfer 条件检查（+5 行 -2 行）

影响

• onlyTransfer=true 模式：协同窗口不再显示，协同模块网络监控不启动，断网仅弹一个提示框
• 正常协同模式（onlyTransfer=false）：行为完全不变
• 基础服务：regist 等基础服务在 onlyTransfer 模式下仍正常执行

Reviewer's guide (collapsed on small PRs)

Reviewer's Guide

Updates cooperation plugin startup so onlyTransfer=true runs shared registrations without creating the cooperation window or its duplicate network monitor, leaving the data-transfer monitor as the sole disconnect notifier; standard cooperation mode is unchanged.

File-Level Changes

Change	Details	Files
Conditionally disables cooperation UI startup and network monitoring in transfer-only mode while preserving plugin registration and normal-mode behavior.	Reads the application-level onlyTransfer property once at startup. Skips showing the cooperation window and starting MainController when transfer-only mode is enabled. Continues registering core, transfer, and cooperation services; leaves first-start handling and normal cooperation mode unchanged.	src/plugins/cooperation/core/cooperationcoreplugin.cpp
