/**
 * This workflow updates a cart's promotions, applying or removing promotion codes from the cart. It also computes the adjustments
 * that need to be applied to the cart's line items and shipping methods based on the promotions applied. This workflow is used by
 * [Add Promotions Store API Route](https://docs.medusajs.com/api/store#carts_postcartsidpromotions).
 *
 * You can use this workflow within your own customizations or custom workflows, allowing you to update a cart's promotions within your custom flows.
 *
 * @example
 * const { result } = await updateCartPromotionsWorkflow(container)
 * .run({
 *   input: {
 *     cart_id: "cart_123",
 *     promo_codes: ["10OFF"],
 *     // imported from @medusajs/framework/utils
 *     action: PromotionActions.ADD,
 *   }
 * })
 *
 * @summary
 *
 * Update a cart's applied promotions to add, replace, or remove them.
 *
 * @property hooks.validate - This hook is executed before all operations. You can consume this hook to perform any custom validation. If validation fails, you can throw an error to stop the workflow execution.
