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.
