One bonus technique related to the “move to a third package” advice: generating many of your model structures (SQL, Protobuf, graphql, etc) allows you to set up obvious directionality between generated layers and to provide all generated code as “base packages” to your application code, which then composes everything together.

Prior to this technique we often had “models importing models circularly” as an issue but that’s entirely disappeared due to the introduction of the structural additional layer.
