- Nuevo módulo `auth` que exporta `CurrentUser`, `CheckPermission` y `has_permission()`. - `Context` y `Page` exponen `current_user()` vía `Contextual`. - `HttpRequest` accede a extensiones de middleware con `extension<T>()`. - `Extension` incluye nuevo método `configure_middleware`. - `try_dispatch_actions` para despachar acciones con control del flujo.
