feat(astro): update Cloudflare support for Astro 6

[AmanVarshney01]

Updates Alchemy's Astro Cloudflare support to match Astro 6 output and adapter conventions.

Changes

• switch Astro Cloudflare server defaults to dist/server/entry.mjs
• switch Astro Cloudflare assets defaults to dist/client
• update Astro package support to Astro 6 and @astrojs/cloudflare 13
• update the Astro template package versions and Wrangler template paths
• normalize the Astro plugin's local Cloudflare proxy config for the v13 adapter API

could this also update the cloudflare-astro example?

[sam-goodwin]

Does it still work for older astro?

[AmanVarshney01]

Yeah, this would break Astro 5.

Astro 5 still outputs:

dist/_worker.js/index.js

I’m not sure we can reliably infer v5 vs v6 inside the resource

I thinkmaybe we just update the docs?

keep these defaults aligned to Astro 6
document the Astro 5 override explicitly

Something like:

await Astro("website", {
  entrypoint: "dist/_worker.js/index.js",
  assets: "dist",
  wrangler: {
    main: "@astrojs/cloudflare/entrypoints/server.js",
  },
});

maybe a version prop? we default to astroVersion: 5 so we don't break it for existing users and anyone who wants to use astro 6 would explicitly say astroVersion: 6.

or we just version the entire resource but that feels like overkill. We should really avoid breaking userspace
