Strip all x-middleware-* prefixed headers from responses in both the App Router and Pages Router dev servers before sending to clients. These headers are internal routing signals (x-middleware-next, x-middleware-rewrite, x-middleware-override-headers, etc.) and should not be visible to end users. The prod server already stripped these correctly. This brings the dev servers into parity.
