+## 修复

+- 优化模型选单的拥挤布局：模型名单独一行，协议和「读图」标签放在下一行，连接状态保持完整；长服务商地址不再撑出横向滚动条（#15040，关联 #15012）。
+- 合并工作台新标签页中重复的「资源管理器」和「文件…」入口；打开资源管理器即可直接搜索文件（#15040）。

+## Fixed

+- Model names have their own line; protocol and image badges sit below without squeezing connection status. Long provider endpoints stay within the menu (#15040; refs #15012).
+- The workbench's duplicate Explorer and Find a file entries are merged. Opening Explorer focuses the file search (#15040).

+- 修复对话向下滚动、展开的「执行过程」标题吸在顶部时，背景是透明的，导致标题和下面滚上来的执行内容叠在一起、两行文字重叠显示的问题：吸顶的标题现在用对话区的底色盖住它下面的内容（#15044）。

+## Fixed

+- When an open "Work" heading stuck to the top while the conversation scrolled, its background was transparent, so the rows scrolling beneath it showed through and two lines of text overlapped. The stuck heading is now painted in the conversation's own colour (#15044).

+- 修复技能目录里的文档文件（比如 `skills/某技能/README.md`、`skills/某技能/子目录/README.md`）被误报成"没有描述，会加载但不会出现在技能索引里"的警告弹窗：这些嵌套的文件本来就不会被当成技能，现在只对真正保留下来的技能说这句话（#15045）。

+- Documentation files inside a skill folder, such as `skills/some-skill/README.md` or one a level deeper, no longer raise the warning that a skill "has no description: it will load but won't appear in the skills index". Such nested files are never loaded as skills; the warning now appears only for a skill that is kept (#15045).
