web/request-handler.sx: configurable SX handler called by OCaml server.
Detects AJAX (SX-Request header) and returns content fragment (no shell)
vs full page with shell. All routing, layout, response format in SX.
OCaml server: http_render_page calls sx-handle-request via CEK.
No application logic in OCaml — just HTTP accept + SX function call.
signal-condition rename: reactive signal works, condition system uses
signal-condition. Island SSR renders correctly (4/5 tests pass).
WASM JIT: no permanent disable on failure. Live globals.
WIP: page-sx empty in SX handler — client routing needs it.
Navigation tests timeout (links not found after boot).

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.
