DTK0034: Duplicate DevTools Plugin

Message

Vite DevTools has been registered multiple times.

Cause

More than one Vite DevTools plugin instance was added to the same Vite configuration. This can happen when both the user and a framework register DevTools, or when the plugin is listed more than once.

Fix

Remove the duplicate Vite DevTools registration.
