errors: raise StateError when push fails because it creates new heads

I decided to raise `StateError` here because the local and remote
repos are in an incompatible state. I think remote errors (exit code
100) should be when something goes wrong on the remote and there's
nothing the user can do.

This directory is meant to cache artifacts useful for tests (such as bundle).

Those artifacts need to be cached because they are slow to regenerate on each
test but too large to be tracked within the repository. They are not expected
to change between each run and can be cached.

The `./scripts/` contains code to generate the artifact while the `cache`
directory contains resulting artifact.
