 3. 在“2925 基邮箱”右侧打开 `号池` 开关后，基邮箱输入框会切成下拉框，只能从 2925 账号池中选择邮箱；关闭开关则回退到原来的手填基邮箱路线

+5. 只有在 `号池` 开关开启时，自动流程执行到 Step 4 / Step 8 前才会自动检查 2925 登录态；如果未登录，会直接使用当前账号自动登录；点击登录后若 `20 秒`内仍未进入收件箱，则会判定当前登录失败
 6. 当 Step 4 / Step 8 轮询邮箱时遇到“子邮箱已达上限邮箱”，扩展会记录当前时间；如果还有下一个可用账号，就禁用当前账号 24 小时并自动切换登录；如果没有下一个可用账号，或当前未启用号池模式，则会直接复用现有“手动暂停 / 停止”逻辑终止自动流程
 7. 如果你同时开启了 `Auto` 的自动重试，当前尝试结束后会按现有逻辑自动进入下一次尝试，不需要再手动介入
 8. `Mail = 2925` 仍然走 Gmail / 2925 共用的别名邮箱链路；实际注册邮箱会基于当前 2925 账号邮箱生成，例如 `name@2925.com -> name123456@2925.com`
