✨ feat(vscode): 新增「了解一块代码」：AI 找功能代码占一栏，对话里接着改
主栏标题栏的放大镜问要了解哪一块，占一个栏位建一栏（和收藏共用 30 个栏位，视图改名 slot1..30，按 slotKindN 分收藏 / 功能挂标题栏按钮），同时开对话页让 Claude 只读地在全部工作区文件夹里找，按 --json-schema 交回环节 → 文件 + 符号 + 一句话。 对话复用预览顶部的聊天（CodeQa.askTop：会话续接、进行中的一轮、记录存 workspaceState）；结构不合格算这一轮没答成、留着能再画出来。 条目每次画、点时按眼下的代码找：有语言插件的解析成代码块按「类名.方法名」找，没有的问 VS Code 文档符号；找不到画成灰的。

* 「了解一块代码」的侧栏：主栏标题栏的放大镜问要了解哪一块，占一个栏位（和收藏共用）建一栏，同时让 AI 在整个工作区里找；
|

* 对话放在这个功能的对话页上（预览顶部的聊天，记录、进行中的那一轮都归 CodeQa 管），接着说就按上次的会话改、整栏换成新结果。
|

* 栏里是 AI 交回的各个环节和条目；条目每次画、每次点时按眼下的代码找位置，找不到的画成灰的。
