[BUG?]: Throws error "Server is not running" as server.close already ran

I'm using [`@astrojs/cloudflare": "14.2.5"`](https://npmx.dev/package/@astrojs/cloudflare) which when building fails with an error "Server is not running.", which I've narrowed down to here:

https://github.com/cloudflare/workers-sdk/blob/5377aaed47144ef5dc873d77a4e3aba0d0232f7c/packages/miniflare/src/plugins/core/inspector-proxy/inspector-proxy-controller.ts#L334-L337

From my interpretation, `server.closeAllConnections()` is ... closed the servers connections (duh... hence the name), but then the following `server.close()` is throwing an error as there is no server left to close 🤷...

Seems a bit string to "throw" when the valid outcome occurred.

(With: Bun v1.4.0 & Wrangler v4.126.0)

Start in packages/miniflare/src/plugins/core/inspector-proxy/inspector-proxy-controller.ts at lines 334-337 and reproduce the failure by building the Astro Cloudflare integration with the reported Bun and Wrangler versions. Trace the server shutdown path and verify that a server whose connections were already closed does not make the build fail with “Server is not running.”
