nx_edge_serve_static.nx

nx_edge_serve_static.nx -- substrate primitive that turns a CONNECTED Tls13ServerSession into a one-shot HTTPS serving call. What this ships: nx_edge_build_http_response(content, content_len, out, out_cap) Builds a minimal HTTP/1.1 200 OK response with Content-Length header and the given body. Returns total bytes written. nx_edge_serve_static_response(session, content, content_len, out, out_cap) After handshake completes (state CONNECTED), this builds an HTTP/1.1 response wrapping `content` and AEAD-encrypts it as a TLS application_data record under server_app_traffic_key + iv. Returns total bytes written to `out` (the wire bytes to send to the client over the TCP socket). This is the final substrate brick between the substrate's TLS 1.3 server arc (10 stones + app_send/recv shipped) and an operator- runnable HTTPS daemon.
