A bar keeps one agents panel across the widget rename
A bar that still had omarchy.model-usage, and took both agents migrations at once, showed two panels side by side. The earlier migration merged into quattro treats that old id as the widget already there. A bar that already has two panels is not cleaned up.
A bar that still had the agents widget under its old id, omarchy.model-usage, and took both agents migrations in one update ended up with two panels side by side.
The earlier migration treats the old id as the widget already being on the bar, and the rename migration carries that entry over. A bar that already has two panels is not cleaned up. Replaying both migrations against a tray and model-usage config left two agents entries before the change and one after. The pull request merged into quattro.
