Proposed Changes

• Remove default Hello wp-now "virtual" index.php
• Avoids remounting directories, which prevents PHP runtime crashes during rotation.

Why?
It seems in the past the rotatePHPRuntime was starting a fresh Playground that needed mounting the directories, and that's not the case anymore.

Testing Instructions

• Apply this diff to reduce the number of requests that produces a PHP runtime rotation.

• Run npm start
• Start a site
• Access wp-admin, index, and other pages/posts multiple times
• Observe the message Recreating and rotating PHP runtime every ~10 PHP requests.

I've also observed that the message Stopped watching for file changes but I confirm that the file changes are still working. I edited the main index.php and I saw the changes applied correctly in the browser.

Pre-merge Checklist

• Have you checked for TypeScript, React or other console errors?
