Support importing from GitHub Copilot 支持从GH Copilot导入对话

[calsys456]

We use vscode + copilot, which can export its conversation into JSON with Cmd+Shift+P "Chat: Export Chat...". I wish if Mem can import it, so the knowledge can be migrate and become useful.

我们平时用vscode + copilot，它可以通过Cmd+Shift+P "Chat: Export Chat..."来把对话导出成JSON。我希望Mem可以支持导入这种格式的JSON，这样我的工作知识就可以方便地使用Mem进行总结和迁移了

For convenience, here's an example of exported JSON from one of my conversation

随附一份我自己的对话导出结果，或许能对你们的开发起到便利

Thanks for raising this, and welcome. We are actively pushing Copilot support forward, and I have added this to today’s issue sweep plan as part of the “acknowledge + backlog / implementation path” set.\n\nShort version: desktop-managed Copilot integration is landing, but full GH Copilot conversation import still needs a clean end-to-end product path so it does not become a one-off importer. We will keep this issue updated as that path firms up.
