More comprehensive CI checks

[ekohandel]

Project Improvement

The current CI system only checks doc and build/test targets of crates. In order to provide more assurances, we should also be checking lints, and formatting of the code.

It would also be valuable to have semver checks to more easily flag backward compatibility issues.

Other context

As part of this effort we should also consider moving to GitHub Actions
