@clerk/astro doesn't support Astro v6 in Cloudflare - Error: Astro.locals.runtime.env has been removed

[asdfjkalsdfla]

Description

When running the @clerk/astro middleware with cloudlfare, it produces the following error -
Error: Astro.locals.runtime.env has been removed in Astro v6. Use 'import { env } from "cloudflare:workers"' instead.

Looks like https://github.com/clerk/javascript/blob/2627442c1c38a5211bdcd707ca19b156c6a63e11/packages/astro/src/server/get-safe-env.ts need to be updated. The calls were removed in the Cloudflare adapter (withastro/astro#14306) and now produces an error (withastro/astro#15075).

Potential patch. This support simple node runtime variables as well.

// At the top of the file, attempt to import cloudflare:workers env
// This will only succeed in Cloudflare Workers runtime with Astro v6+
let cloudflareEnv: any = undefined;

// Use a self-executing function to avoid top-level await
(async () => {
 try {
 const cf = await import('cloudflare:workers');
 cloudflareEnv = cf.env;
 } catch {
 // Not in Cloudflare Workers environment or module not available
 }
})();

/**

 * Isomorphic handler for reading environment variables
 * Supports:

 // Node.js / Vercel SSR: check process.env
 if (typeof process !== 'undefined' && process.env?.[envVarName]) {
