fix: automatically remove projects with non-existent paths

When a project fails to initialize because the directory no longer exists
(e.g., test artifacts, deleted folders), automatically remove it from the
project list instead of showing the error repeatedly on every reload.

This prevents users from being stuck with broken project references in their
settings after testing or when project directories are moved/deleted.

The user is notified with a toast message explaining the removal.
