## Summary by CodeRabbit

* **Tests**
  * Simplified dependency handling by removing module-level import guards and using runtime checks that skip tests when optional ML libraries are unavailable.
  * Deferred importing of optional config/components until after runtime checks to prevent import errors and maintain consistent test behavior when dependencies are present.
