/**
* 【API 语言协商中间件】
*
* - 挂载位置bootstrap/app.php 中对 api 分组 prepend所有 /api/* 请求都会先执行本中间件。
* - 职责:解析客户端语言 写入 $request->attributes['lottery_locale'] 调用 app()->setLocale()
* 便于 trans()、LotteryMessage 及后续按 zh/en/ne 选库表文案列时使用。
*
* 【协商顺序】① 请求头 X-Locale必须为 config 支持的 zh/en/ne 之一);② Accept-Language 首选项;③ fallback。
*
* 【与前端】浏览器或 App 可直接带 X-Locale或仅靠 Accept-Language无需前端维护文案 JSON。
