glTF viewer executable (windows/linux/mac)

I would appreciate to have a great glTF viewer for Windows (11). Just like the [3D-Viewer](https://apps.microsoft.com/store/detail/3dviewer/9NBLGGH42THS) (shipped with Windows 10+). but better (3D-Viewer doesn't work with open-with in Windows 11 and models just not rendered correctly). What do you think? We could wrap this in [Electron](https://www.electronjs.org/) to build for platforms like Windows, Linux and MacOS. Or write it in another language. WIth drag and drop and open with file (start argument). Does that already exist? Did I miss something?

Start by reviewing the existing glTF Sample Viewer and investigating whether an Electron-based desktop wrapper can support Windows, Linux, and macOS. Check the requested drag-and-drop and open-with behavior, then define a concrete platform scope and acceptance criteria for a standalone executable.
