Optimization Events

Compute steps emit EnOptEvent objects at lifecycle milestones. Event handlers (ResultsHandler, CallbackHandler, etc.) consume these events to track progress, store results, or trigger user logic.

See Working with Results for an example of subscribing to events, and EnOptEventType for the available event types.
