Not sure what corporate hellscape you live in but that is not how it works at all.
If you left it as a public git repo you just have to point to the commits in your repo as existing before their product and the case falls flat.

Without a license, a company can take your code, compile it into a program, publish that under a different name, slap their own proprietary license on it which prohibits free use, and then sue you, the developer, for copyright infringement.
Applying a license such as GPL to your open source code makes that legally impossible.

No. All rights reserved is default. And as copyright is mostly harmonised around the world, I doubt there is any country where that is not the case.
