// Trae-Toolbox oss-browser 包装层（resources/app/main.js）
// 作用：启动时读取 exe 同目录 trae_default_oss_path.txt（第1行 oss 路径，第2行可选 region），
//       并从本机 ~/Toolbox_local_creds.env.local 读取 DOC_CLOUD_KEEPER_OSS_* 凭据（运行时读取，零硬编码），
//       注入渲染进程：写入 AuthInfo 并补丁 $rootScope.currentAuthInfo / bucketMap，
//       使 oss-browser 每次启动即以有效账号登录、地址栏自动定位到默认目录；
//       随后原样交接给官方 app.asar 内的 main.js，不改动官方包任何字节。
// 卸载：删除 resources\app 目录与 trae_default_oss_path.txt 即恢复原版。
