Phase 6: 一键多开 (工具组合) 功能

- 数据模型: ToolItem 新增 IsGroup(bool) + SubToolIds(List<string>) 字段

- 执行逻辑: ProcessExecutionService 改为 ExecuteAsync, 组合卡片遍历子工具逐一启动(500ms延迟), 孤儿ID跳过并打印警告

- 组合编辑: GroupEditViewModel + GroupEditWindow, 复选框列表勾选非组合工具

- 主界面: 标题栏新增 '+添加组合' 按钮(蓝色), 组合卡片右下角显示 📦 角标

- 右键菜单: 区分 '编辑工具' (普通) 和 '编辑组合' (IsGroup=true)

- 快捷键: HotKeyManager 适配 ExecuteAsync 异步调用

- 测试: 82 tests total (ProcessExecution 4->6, GroupEdit 5 new)
