What's Wrong?

As I also explained in the title, I'm trying to attach files with @ that are in my src folder but they are not appearing there, everything else outside of that folder is available.

Also I have this behaviour only in plugin, the terminal app works fine.

What Should Happen?

I should be seeing files that are under src as well.

Steps to Reproduce

1. Open your IDE with the Claude Code plugin enabled.
2. Ensure your project contains a src folder with at least one file inside (e.g., src/main.py).
3. Attempt to attach/reference a file from the src folder using the @ symbol in any Claude Code input (e.g., "Open @src/main.py").
4. Observe that no autocomplete or file picker options appear for files inside the src folder.
5. Try the same attachment/reference operation for a file outside the src folder (e.g., README.md), and note that autocomplete and attachment work as expected.
6. Repeat the attachment using Claude Code from the terminal (CLI) with the same src folder and observe that attachment works for all files.
