What's Wrong?

When using the VSCode extension, trying to add files as context with @ looks up files that are in my .gitignore_global config:

<img width="662" height="404" alt="Image" src="https://github.com/user-attachments/assets/d537a953-23b8-4ad4-a6e4-4045f5648650" />

When I try the same in claude code in the terminal I do not get this issue (.gitignore_global is respected). This is in the same repo for both:

What Should Happen?

Claude should respect my .gitignore_global when adding files to the context with @ from both the terminal and VSCode extensions

Steps to Reproduce

1. Create ~/.gitignore_global, add files to it, and set that as global with git config --global core.excludesFile ~/.gitignore_global
2. Create files that are ignored (in my case it is files created by the local history extension)
3. Start a chat with cmd+esc in VSCode, using the extension UI (not terminal UI)
4. Add a file with @ and see that the extension suggests files that are gitignored
