/**
 * This script is used to reset the project to a blank state.
 * It deletes or moves the /app, /components, /hooks, /scripts, and /constants directories to /app-example based on user input and creates a new /app directory with an index.tsx and _layout.tsx file.
 * You can remove the `reset-project` script from package.json and safely delete this file after running it.
