Description

We have now have some, but we could always use more jump/SDE/ODE/event hybrid models to add as correctness tests (preferably which aren't so expensive they kill CI).

Contributor guide

Research direction
Examine the existing correctness tests for hybrid models (jump/SDE/ODE/event) in the repository. Understand the test infrastructure and add new tests for similar systems. Ensure the tests are not computationally expensive for CI.
