Add an Astro integration to inject modulepreload hints

Astro doesn't emit <link rel="modulepreload"> tags, so browsers discover JS dependencies one hop at a time. A Vite plugin now walks the client chunk graph at build time and injects a dependency manifest; an Astro middleware reads it and injects modulepreload hints into every HTML response, letting the browser fetch all modules in parallel from the first HTML parse.

For context, see withastro/roadmap#561
