/add-dir does not add folders when copilot is started in one repo

[sezerb]

Describe the bug

When start in one repo, then add others, the folders are not added, listed in copilot cli.

Affected version

GitHub Copilot CLI 0.0.420.

Steps to reproduce the behavior

Start in one repo, then add others (requires full paths)

copilot
/add-dir /Users/me/projects/backend-service
/add-dir /Users/me/projects/shared-libs
/add-dir /Users/me/projects/documentation

Then list the folders:

/list-dirs

It only lists starting repo.

Expected behavior

When copilot started in one repo and I add other directories and list them, they should be listed.
