Bug: Persistent Worktree creation failure leaves an undeletable loading project

What issue are you seeing?

Summary

Creating a Persistent Worktree fails and leaves behind a permanently loading Project that cannot be removed from the sidebar.

Even after the worktree creation fails, the partially created Project remains visible with a spinning/loading indicator and provides no context menu or delete option.

Restarting ChatGPT Desktop does not resolve the problem.
