Cannot select source file to include in chat window via 📎 file list button when the build is out of source

[ebernardatdxo]

Describe the bug
Our project is configured to have the build directory out of the source directory.
And the xcode project is generate by cmake.
The tree is like that :

    project_src
    project_build
        project.xcodeproj
        bin 
        etc ...

In this configuration copilot don't list file from the source directory.
It only list file from the build directory.

Versions

• Copilot for Xcode: [e.g. 0.32.0]
• Xcode: [e.g. 16.2]
• macOS: [e.g. 15.3.2]

Steps to reproduce
clic on 📎 and only files inside the project_build appear.
