油猴插件--一键0.52刀买team

用法：

打开 Tampermonkey 新建脚本。
粘贴这个文件内容保存。
访问：
https://chatgpt.com/codex/team/checkout?checkout_from=codex_app
页面右下角会出现按钮：
执行 checkout/update quantity=13
等页面出现有效 checkout_session_id 后点按钮。
注意：如果右下角显示：

当前 checkout_session_id: (未检测到，等页面跳转后再点)
说明当前 URL 还是 /checkout?..，还没拿到真正的 checkout session id，不能点。
