giles 671d19c978 SX request handler + AJAX nav + shared JIT globals + shell cleanup
- Remove prism.js, sweetalert2, body.js, sx-browser.js from shell —
  only WASM kernel (sx_browser.bc.wasm.js + sx-platform.js) loads
- Restore request-handler.sx integration: SX handles routing + AJAX
  detection, OCaml does aser → SSR → shell render pipeline
- AJAX fragment support: SX-Request header returns content fragment
  (~14KB) instead of full page (~858KB), cached with "ajax:" prefix
- Fix language/applications/etc page functions to return empty fragment
  instead of nil (was causing 404s)
- Shared JIT VM globals: env_bind hook mirrors ALL bindings to a single
  shared globals table — eliminates stale-snapshot class of JIT bugs
- Add native `parse` function for components that need SX parsing
- Clean up unused shell params (sx-js-hash, body-js-hash, head-scripts,
  body-scripts, use-wasm) from shell.sx, helpers.py, and server.ml

14/32 Playwright tests pass (navigation, SSR, isomorphic, geography).
Remaining failures are client-side (WASM bytecode 404s block hydration).
