What's Wrong?

When launching claude from VScode integrated terminal (Powershell or Git Bash at least), three VScode windows are opened just after trusting the current folder.

I tried to:

• Re/install @anthropic-ai/claude-code NPM package;
• Re/install native claude code app with claude install;
• With and without anthropic.claude-code VScode extension;
• Clean install my whole computer (yup, I'm serious);

Seems to relate to #7680.

What Should Happen?

It should not open other VScode windows.
