malyawka/Unity-Mesh-Info ? reverse-engineered prompt

Build me a simple Unity editor tool that lets me inspect mesh data in a dedicated window.

I want to open it from the Unity menu under Window, then Mesh Extensions, then Mesh Info, and have it show useful details for whatever mesh I select. It should feel like a clean editor utility, not a full game feature. The main goal is to quickly view mesh information in one place, with a straightforward interface that updates when I pick a different mesh.

Please make it work as a small reusable editor extension, and include any shader or editor support needed so the preview looks good. If you need to check current Unity editor APIs or best practices, look them up online first.
