feat: add a basic CI script

This just makes sure the code compiles and passes some static analysis, doesn't run the tests since a lot of them hang on my system

fix: remove branch restrictions for pull_request events in CI workflow

forgot we don't push to main, my bad.
if we had a dev branch I could filter it to only run on main and dev but since the "dev" branch changes every release let's just run it everywhere

fix: specify cache-dependency-path

fix: add concurrency settings to CI workflow

only one run at a time per ref
