AI Summary: The task is to fix a bug in the Kotlin OpenFeature SDK's `setEvaluationContext` function. Currently, updating a mutable map of attributes within the context doesn't trigger a context change. The solution involves implementing a proper map diff to detect changes and only update the context when necessary.

AI Summary: Implement support for multiple feature flag providers in the Kotlin OpenFeature SDK, allowing users to integrate and delegate evaluations across several providers within a single application. This involves designing and implementing the necessary logic to manage and switch between providers, potentially using a strategy pattern or similar design to handle provider selection and evaluation. The implementation should align with the OpenFeature specification's multi-provider concept and consider aspects like provider prioritization, error handling, and context propagation.
