Archived projects persist after GitHub repo deletion

Description

Archived projects in the Claude Code mobile app continue to show in the "Archived" section even after the linked GitHub repository has been deleted. There's no way to manually remove them from the list.

Steps to reproduce

1. Create a project in Claude Code linked to a GitHub repo
2. Archive the project
3. Delete the GitHub repo (via gh repo delete or GitHub UI)
4. Open Claude Code mobile app — the archived entry still appears

Expected behavior

Archived projects should either:

• Automatically disappear when the linked repo no longer exists
• Provide a manual "Remove" option (swipe, long-press, or menu)

Actual behavior

The archived project entry persists indefinitely with no way to remove it. Force-quitting and reopening the app does not help.

Environment

• Claude Code mobile app (iOS)
