feat(agent): enhance online Agent functionality with improved read-only responses and log view

docs/content/docs/progress/pending-test.mdx

@@ -8,3 +8,6 @@ description: 当前版本已实现但仍需人工验证的变更项
 - 右上角 `Agent` 按钮在面板已打开时再次点击会走与右侧收起图标一致的收起动画，不再立即卸载面板；需要验证打开、右上角再次点击收起、右侧收起图标收起和收起过程中再次打开都正常。
 - 右侧 `Agent` 面板默认打开宽度已调大；需要验证首次打开空间更宽，手动拖拽调整宽度仍正常。
 - 在线 `Agent` 输入框底部的文本模型控件改为无背景无阴影的轻量下拉，只展示图标、模型名和渠道，并移除了输入区上方分割线；需要验证能正常切换文本模型。
+- 在线 `Agent` 询问“画布里有什么内容”等只读问题时不再进入工具确认流程；需要验证只展示普通回答，不出现“等待确认”工具卡片。
+- 在线 `Agent` 连接文本节点和生成配置节点时会把 `Note`、`生成配置` 等别名归一化为真实节点 id，模型漏传连接端点时也会回退到当前画布的文本节点与生成配置节点；需要验证不会再因标题当 id 或空端点而失败。
+- 在线 `Agent` 日志页改为类似本机 Agent 的可复制诊断日志视图；需要验证排查日志、原始 JSON、复制、最近错误和清空操作正常。
