- Combine editingId + editingName into single editing: { id, name } | null state object
- Extract cancelEdit() helper called in 3 places instead of repeating setEditing(null)
- Tag all update-name action responses with intent: "update-name" so errors can be
identified and routed correctly
- Show update-name errors inline below the edit input
- Guard single-add and bulk-add error displays against showing update-name errors
