feat(client): 标签 TSPL 裸发支持 Windows（winspool WritePrinter）

- 抽出 _findThermalPrinter（macOS: lpstat -e；Windows: Printing.listPrinters）
  与 _sendRaw（macOS/Linux: lp -o raw；Windows: winspool WritePrinter RAW）
- 新增 _winRawPrint：OpenPrinter/StartDocPrinter(RAW)/WritePrinter 直送裸字节
- 位图渲染与 TSPL 生成跨平台复用；macOS 行为不变
- 依赖新增 win32/ffi（仅 Windows 运行时调用，已 Platform.isWindows 守卫）
