feat: 设备桥共享库 + CLI全能力补齐 + GUI omniparse/computeruse 重构

- 抽取设备桥 WS 协议层为共享库 (internal/devicebridge/client/)
- CLI 补齐 11 项 caps 能力(screensee/screensue/speakeruse/camerasue/...)
- GUI 新增 omniparse 能力(Windows UIA 窗口解析)
- GUI computeruse 改用 koffi 直接调用 user32.dll，不再依赖 PowerShell C# 编译
- GUI computeruse JSON 解析兼容非标准格式 {x:500,y:300}
- 新增 mock-server 用于本地测试设备桥协议
- 新增 GUI DLL 桥接模块 (devicebridge_dll.js)
