"""导出 device_liveness 表里所有 device_id 及其对应的推送 regId,按 push_vendor 分组(本地开发工具)。

用法:
  双击 scripts/show_device_regids.bat,或命令行:
    python scripts/show_device_regids.py [filter]

  [filter] 可选:大小写不敏感的子串,匹配 device_id / push_vendor / push_token /
  registration_id 任一列;不传则列出全部。
    show_device_regids.py xiaomi          # 只看小米
    show_device_regids.py device_Pixel    # 按 device_id 片段找

说明:
- 直接以**只读**方式读 SQLite(server 在跑也不会抢写锁),所以开不开服务器都能用。
- push_token = 各厂商的 regId/pushToken(新链路,当前在用);registration_id = 旧极光
  regId(历史兼容)。两列都打出来,方便跟 logcat 现役值逐字比对。
- 输出刻意保持纯 ASCII 排版并竖排展示**完整值**:双击弹出的 cmd 走 GBK 码页,竖排纯
  ASCII 不会乱码;完整值不截断,才能直接复制去比对。
- 若 DATABASE_URL 不是 sqlite(生产 postgres),这里只提示改用 psql。
