Codex Desktop App: Cannot recover moved project ("Current working directory missing")

Product

Codex Desktop App (macOS)

What happened

In the Codex Desktop App, after moving a project folder on disk, this thread shows:

Current working directory missing
This thread's working directory no longer exists because I moved the folder

At that point, I can’t relink the project to its new location from the UI.

Expected behavior

When a project path is missing, Codex Desktop App should offer a recovery action to update the path (for example in the ... menu):

• Change Path... / Relink Folder...

Steps to reproduce

1. Open a project/thread in Codex Desktop App.
2. Move or rename the project folder in Finder/terminal.
3. Return to Codex Desktop App.
4. Observe the "Current working directory missing" message.

Requested fix

Add a way to select the new folder path and relink the existing project/thread without deleting and recreating it.

Why this matters

Removing and re-adding the project is disruptive and risks losing project-level setup/context. Repointing the path would make this recovery fast and safe.

Acceptance criteria

• Missing-path state includes Change Path... action.
• User can select new folder and continue in the same project/thread.
• Existing metadata/settings are preserved.
• Clear error shown if selected path is invalid.
