/**
 * Get a per-request QueryClient for Server Components.
 *
 * Uses React's cache() to ensure the same QueryClient instance
 * is returned throughout a single server request. This allows
 * multiple server components to share prefetched data.
 *
 * @remarks
 * React's `cache()` memoization applies only when called during a React Server
 * Component render. Calling `getServerQueryClient()` outside an RSC context
 * (for example in route handlers or standalone server utilities) bypasses this
 * request-scoped memoization and creates a new QueryClient instance per call.
 *
 * @example
 * ```tsx
 * // app/products/layout.tsx (Server Component)
 * import { getServerQueryClient } from "@techsio/storefront-data/server/get-query-client"
 *
 * export default async function Layout({ children }) {
 *   const queryClient = getServerQueryClient()
 *   await queryClient.prefetchQuery(...)
 *
 *   return (
 *     <HydrationBoundary state={dehydrate(queryClient)}>
 *       {children}
 *     </HydrationBoundary>
 *   )
 * }
 * ```
