[VS Code] "+" (new chat) button resets conversations in ALL open windows

[522725190]

Environment / 环境

• Kimi Code VS Code extension
• OS: macOS
• Multiple VS Code windows open at the same time / 同时打开多个 VS Code 窗口

Problem / 问题
When several VS Code windows are open, each with its own Kimi Code chat panel, clicking the "+" (new chat) button in the top-right corner of one panel resets the conversations in ALL windows — not just the current one. The ongoing conversations in the other windows are lost.

同时打开多个 VS Code 窗口（每个窗口都有 Kimi Code 对话面板）时，在任意一个窗口点击右上角的 “+” 新建对话按钮，会把所有窗口的 Kimi Code 对话全部重置，其他窗口正在进行的会话内容被清空。

Expected / 期望

1. The "+" button should only create a new conversation in the CURRENT window (window-scoped); and/or
   “+” 按钮应只在当前窗口新建会话（按窗口隔离）；
2. Or provide a setting to hide/remove the "+" button to avoid accidental clicks.
   或者提供设置项，可以隐藏/去掉右上角 “+” 按钮，避免误触。

Steps to reproduce / 复现步骤

1. Open two VS Code windows, each with an ongoing Kimi Code conversation.
   打开两个 VS Code 窗口，各自进行 Kimi Code 对话。
2. Click the "+" button in one window.
   在其中一个窗口点击右上角 “+”。
3. The conversation in the other window is reset as well.
   另一个窗口的对话也被重置了。
