* Refactor `IndexTriggersAsync` to use `WorkflowDefinition` and update null assignment for serialization logic. * Change default parameter value from `default` to `null` in `UseFluentStorageProvider` method signature. * Add in-memory workflows provider and materializer for integration tests Introduced `InMemoryWorkflowsProvider` and `InMemoryWorkflowMaterializer` to support integration testing scenarios for workflow definition population. Enhanced workflow handling with fluent method `WithId` for `WorkflowBuilder`. Updated event publishing and dependency injection logic. * Remove extraneous whitespace in DefaultWorkflowDefinitionStorePopulator. * Refine test class documentation for `WorkflowDefinitionStorePopulation` scenario.
