 - `collect()` 先读取状态再决定是否读取标题/封面。`task.collection_scope=normal_only` 时，未上架、审核中、状态未知返回 `collection_skipped=True` 和中文原因，不下载封面、不覆盖旧内容；`all` 时四类状态都继续采集。两种策略都重新读取页面状态，不能用历史状态预过滤。结束时只关闭本轮自动新建的商品编辑页 tab，并通过 `close_tab_and_wait()` 在最多 2 秒内确认 target 从 `/json` 消失，结果写入 `close_target_confirmed`。确认超时只记警告，不覆盖已成功读取的标题/封面；如果 `open_product()` 尚未返回就失败，也由 `open_product()` 关闭本轮自动新建 tab；用户原本打开的商品 tab 不关闭、不等待。
 - ③ 更新流程中程序自动新建的商品编辑页成功/失败都关闭，复用用户原本打开的 tab 只断开 CDP、不关闭页面；`open_product()` 内部打开失败的新建 tab 仍由 `open_product()` 自行关闭。Shopee 确认成功后可能把当前 tab 跳回 `/portal/product/list/all?operationSortBy=modified_time`，`click_update()` 会把该 URL 记录到 `post_update.url` 并标记 `redirected_to_list=true`；自动新建页成功关闭前等待 2 秒。
