🤖 feat: show deletion feedback in workspace sidebar (#819)

_Generated with `mux`_

When a workspace is being deleted, the UI now provides visual feedback:

- **Dimmed row**: The workspace row becomes 50% opacity
- **Disabled interaction**: Click/hover disabled during deletion
- **Status message**: Shows '🗑️ Deleting...' in place of normal status

Works for both regular and force-delete flows.
