Split journey tests out into their own CI job

In the `justfile`, this renames the old `ci-test` recipe to
`ci-test-full`, and has `ci-test` no longer clean the target
directory nor run journey tests.

The CI `test` job thus remains the same, but it does moderately
less work. A new CI job, `test-journey`, is introduced to run the
journey tests (still via `ci-test-journey` recipe).

This change is intended to allow greater parallelism, and possibly
make caches work better. The CI `test` job has sometimes been a few
minutes slower than before, ever since 5173e9a (GitoxideLabs#1668). See
comments in GitoxideLabs#1668 for some discussion on this change.
