 GUI 二进制输出到 `build/bin/huya-gui`。开发时可以使用 `wails dev` 启动 Wails + React + Ant Design 界面。
 
+Windows exe（文件名带版本号）：

+```bash
+./scripts/build-windows.sh          # 默认 windows/amd64
+./scripts/build-windows.sh arm64    # 如需 windows/arm64

+
+产物为 `build/bin/huya-gui-v<版本>.exe`（PE32+ GUI）。版本号的单一来源是 `internal/version/version.go`：脚本从这里读取版本号，既拼进 exe 文件名，也通过 `-ldflags "-X huya-go/internal/version.Version=..."` 编译进程序，界面左下角的版本标签来自同一个值。发布新版本时改这一处，并同步 `wails.json` 的 `info.productVersion`（只影响 exe 文件属性）。在 macOS 上交叉编译不会生成 NSIS 安装包（`-nopackage`），只产出 exe。
