GitLab

Flesh out our github actions CI so we can build official releaes.

* remove `-w -s` linker flags on windows

* use `zip` for windows installer compression

Also fixes a few fit-and-finish items for better developer experience

This focuses on Windows first, but coudl be used for Mac
and possibly linux in the future.
