New web/request-handler.sx: configurable SX function (sx-handle-request) that receives path + headers + env and returns rendered HTML. The handler decides full page vs AJAX fragment. OCaml server: http_render_page now just calls the SX handler. All routing, layout selection, AJAX detection moved to SX. Header parsing added. is_sx_request removed from OCaml. Configurable via SX_REQUEST_HANDLER env var (default: sx-handle-request). WIP: handler has parse errors on some URL formats. Needs debugging.
