[BUG] Cowork: detectedProjects fails with "no such column: paths" — disclaimer binary queries non-existent SQLite schema after clean install (macOS, M3)

What's Wrong?

On every Cowork session attempt, the app logs a detectedProjects error caused by the bundled disclaimer helper binary executing a SQLite query against a workspaces table that does not have a paths column. This occurs even after a completely clean install with no prior data.

What Should Happen?

The disclaimer binary should either create the workspaces table with the correct schema on first run, or handle a missing/outdated schema gracefully without throwing.
