Improvement to how the `app` and `pages` files conflict is shown. Especially the last log line `"pages/" - "app/"` made it seem like you should remove the `pages` folder altogether. This was a bug in how the `''` case was displayed. After having a look at this I went further and added exactly which file caused the conflict given that `app` allows you to create `app/(home)/page.js` and such it saves some digging for what the actual conflicting file is. Similarly in `pages` both `pages/dashboard/index.js` and `pages/dashboard.js` are possible.
