+// bgo_uploader.go — an SSHUploader implementation that delegates to the
+// internal `bgo scp` client. bgo is ByteDance's internal credential/auth
+// management tool; it wraps ssh/scp and handles login transparently once the
+// user has configured it (see the Lark guide linked in the Settings UI).
+//
+// 设计理由 (为什么不能直接 exec bgo, 也不能复用 KerberosUploader):
+//   - bgo 强制要求在 PTY (伪终端) 下运行: 它会对 stdin/stdout 做终端 ioctl
+//     (resize pty). 没有 PTY 时直接 panic ("operation not supported by
+//     device"). 因此必须用系统 /usr/bin/script 为其分配一个伪终端:
+//         script -q /dev/null <bgo> scp <src> <user@host:dst>
+//     这样既不引入额外的 PTY 依赖, 又满足 bgo 的运行约束.
+//   - bgo scp 不会自动创建远程目录, 且 bgo ssh 无法执行远程命令 (会 panic),
+//     所以无法像 Kerberos 那样先 `mkdir -p`. 故 bgo 模式只能把文件平铺上传
+//     到远端用户的 $HOME 根目录 (文件名内嵌时间戳保证唯一), 上层 service
+//     负责生成扁平文件名.
+//   - bgo 自带鉴权, 不需要也不应传 GSSAPI / 密码 / 公钥相关的 ssh 选项.
