This commit runs GitHub actions for code cleanliness. Because this includes compare and replace build, this verifies that the commit is buildable and clean. The natives are not rebuilt here (yet) because the GitHub actions runner does not have the cross compiler tools installed. Part of migration to GitHub - Issue #32
