N (from anywhere) or n (in Category panel) opens an inline prompt
to add categories one after another without typing :add-cat each time.
- Yellow border + prompt distinguishes it from item-add (green)
- Enter / Tab adds the category and clears the buffer, staying open
- Esc returns to the category list
- Cursor automatically moves to the newly added category
