feat(usb-release): 统一发布版，Mac + Windows 跨平台支持

基于 Pro 精简结构，去掉 app/ 中间层，core/runtime/data/ 直接在根目录。
- Mac: 启动 U-Claw.command + 重新配置.command（含 Config GUI 首次配置）
- Windows: Windows-Start.bat + Windows-Menu.bat（15 项功能菜单）
- setup.sh: --all-platforms 三平台 runtime, --with-toolkit 下载安装包
- 10 个中国优化技能 (skills/)
- toolkit/ 放 Node.js pkg/msi 供离线装机
