Dists do not fetch transitive modules

[Cervator]

Since we started adding module dependencies to Core as part of its extraction the bare engine repo does not actually produce a full functional zip: it lacks the modules Core depends on. This works fine when running from source since you get full transitive resolution and classpath handling, and via Omega dist since it explicitly requests all modules in the lineup (without transitive lookups)

Unsure if better to throw more resolution at it or come up with a different approach (keeping in mind that the Core situation isn't permanent and Iota may be a thing one day)

SampleBuilderGameplay does work since it specifically is minimal and has no dependency beyond the engine.
