**What**
- Add support for creating a cart with items
- Add endpoint `POST /store/carts/:id/line-items`
- Add `CreateCartWorkflow`
- Add `AddToCartWorkflow`
- Add steps for both workflows
**Testing**
- Endpoints
- Workflows
I would still call this a first iteration, as we are missing a few pieces of the full flow, such as payment sessions, discounts, and taxes.
