I don't think even VSCode does this. Probably not even any package managers I know of? Code signing, yes, but not for organization verification? It's pretty much like a username - anyone can claim it if it is unclaimed?
edit: VSCode has a verified marker for publishers but I don't know how that works or if Cursor does the same.
