用法:
  npm run record:mothership [-- 起始URL]
  npm run record:mothership -- --logged-in [起始URL]
  npm run record:mothership -- --login [起始URL]

模式:
  匿名（默认）  录制公开报价 widget；禁止 dashboard / www.mothership.com/quote（GD-15）
  --logged-in   录制账号登录后查价完整路径；允许登录/dashboard 入口

产出（匿名）:
  .rpa/recordings/mothership-<时间戳>.js
  .rpa/mothership-storage.json

产出（登录后）:
  .rpa/recordings/mothership-logged-in-<时间戳>.js
  .rpa/mothership-logged-in-storage.json

登录后录制说明:
  - 请在 codegen 浏览器中手动粘贴 MOTHERSHIP_EMAIL / MOTHERSHIP_PASSWORD（脚本不自动填）
  - SOP: docs/rpa-mothership-logged-in-sop.md

匿名标准样例: LA 90001 → Dallas 75201
