Function: parseCartCookieValue()

parseCartCookieValue(raw): CartCredentials | null

Parse the raw cart-id cookie value into { cartId, cartSecret }.

• "<uuid>" (no dot, legacy) → { cartId, cartSecret: null }.
• trailing dot ("<uuid>.") → id only, cartSecret: null.
• empty / leading-dot / blank → null (no usable cart id).

string | null | undefined
