IsTasksEmptyRepoHintVisible reads _currentList?.Kind directly, but Kind
isn't itself observed — the NotifyPropertyChangedFor chain only fires
when IsLetClaudeVisible's value actually changes. Switching from a
Smart list to an empty User list without a WorkingDir changes Kind
while IsLetClaudeVisible (and Has*) stay false in both, so the hint
never notified and stayed stale.
