test(e2e): real-browser pass in Playwright Chromium

Browse Source 
Three end-to-end scenarios against a static+SSR test server: the
zero-build page (import map + native ESM, no bundler), the SSR page
(rendered content in the raw response, live after hydration, no mismatch
warnings), and adoption (an expando on the server-rendered node survives
a real render). Renders are raf-batched so assertions poll.

Real Chromium flushed out three fixes happy-dom couldn't see:
- nanoraf called an extracted requestAnimationFrame bare — Illegal
  invocation under strict-mode ESM (sloppy CJS had masked it); wrapped.
- the counter example only routed '/', so serving it from any subpath
  threw; it now has a wildcard fallback.
- hydration mismatch detection is now whitespace-insensitive (the parser
  reparents whitespace, e.g. text after </body>), and page scripts belong
  in <head> when a view owns <body> — same convention bankai v9 used.

CI gets an e2e job with chromium-headless-shell.
