fix: translation too slow

 The Posts and Pages lists show a status column for every target language, including the latest successful translation time and a translation action. The Settings page provides **重新翻译所有内容**, **翻译所有文章**, and **翻译所有分类标签**. Each action shows a confirmation before scheduling a forced refresh of all supported content, only published posts and pages, or only categories and tags; this bypasses persisted translations and consumes Baidu API quota.
 
-The Settings page also shows a live progress panel. It refreshes every five seconds and counts completed post/page and category/tag items for every configured target language. When **重新翻译所有内容** starts a batch, progress resets and counts only translations completed after that batch began, so historical translations do not make a new batch appear complete. Forced retranslation jobs are scheduled one minute apart, so a single WP-Cron request processes at most one batch item instead of timing out while processing every post. Progress reads only local WordPress and translation-table data; it does not send additional requests to Baidu.
+The Settings page also shows a live progress panel. It refreshes every five seconds and reports the latest translation task: full translation, post/page translation, category/tag translation, or a single-post translation. It counts only completed items that belong to that task's queued content and target languages after the task began, so historical translations cannot make a new task appear complete. Forced retranslation jobs begin immediately and are scheduled two seconds apart, so a single WP-Cron request processes at most one task item instead of timing out while processing every post. Progress reads only local WordPress and translation-table data; it does not send additional requests to Baidu.
 
 The **清除已翻译的缓存** action deletes every persisted translation, cancels pending translation jobs, and resets batch progress. The front end then falls back to source content until translations are explicitly queued again; regenerating them consumes Baidu API quota.

 文章和页面列表会显示每种目标语言的状态列，包括最近成功翻译时间和翻译操作。设置页提供 **重新翻译所有内容**、**翻译所有文章** 和 **翻译所有分类标签**。它们会在为相应内容安排强制刷新前显示确认警告；此操作会绕过已持久化的翻译并消耗百度 API 配额。
 
-设置页还显示实时进度面板。面板每五秒刷新一次，统计每种已配置目标语言中完成的文章/页面和分类/标签项目。当 **重新翻译所有内容** 启动批处理时，进度会重置，仅统计该批处理开始后完成的翻译，因此历史翻译不会让新的批处理看似已完成。强制重翻任务会按一分钟间隔排队，单次 WP-Cron 请求最多处理一个内容项，避免一次处理全部文章而超时。进度只读取本地 WordPress 和翻译表数据，不会发送额外请求。
+设置页还显示实时进度面板。面板每五秒刷新一次，显示最近一次翻译任务的进度，覆盖全量翻译、文章和页面翻译、分类和标签翻译，以及单篇文章翻译。进度仅统计该任务启动后、且属于其已入队内容和目标语言的完成项目，因此历史翻译不会让新的任务看似已完成。强制重翻任务会立即开始，并按两秒间隔排队；单次 WP-Cron 请求最多处理一个内容项，避免一次处理全部内容而超时。进度只读取本地 WordPress 和翻译表数据，不会发送额外请求。
