Copilot Extension auto-installs extension in VSCode Profile when chatting

[Tim0Cc]

Does this issue occur when all extensions are disabled?: Yes/No

• VS Code Version: 1.99.3 (Universal)
• OS Version: MacOS 15.3.2

Steps to Reproduce:

1. Setup different VSCode Profiles
2. Install Copilot in Profile A and connect Github Account –> chat working as expected
3. Switch to Profile B
4. Uninstall Copilot
5. Open Copilot Chat
6. Prompt
7. Copilot Extension reinstalls automatically

There should be at least a popup saying: "Copilot isn't installed (for this Profile) yet. Install Extension?"

It also auto-enables when disabled, when prompting.

Just to make it more clear, let me rephrase:
A Chat-Sidebar should not be allowed to install extensions (not from Microsoft, nor from any third-party) without (at least) a(n) (explicit) confirmation step in between.

nor should it change from "disabled" to "enabled" without (at least) a(n) (explicit) confirmation step in between.
