 * Builds a `MiddlewareHandler` that post-processes the rendered response

 * API exposed to users via `astro:i18n.middleware(...)` for the manual
 * routing strategy.
 *
 * Only user middleware goes through this wrapper — `handleRequest`
 * invokes `finalizeI18n` directly as an explicit post-processing step.
