MiddlewareFrame

One frame of a middleware onion: pairs a PSR-15 middleware with the RequestHandler it wraps, so a chain can be assembled as nested handlers (new MiddlewareFrame($m0, new MiddlewareFrame($m1, $terminal))). Calling handle() runs the middleware's process(), handing it the inner handler as $next. Stateless and cheap — a couple of object fields, no clone-per-step.
