Summary of Changes

Hello @kylejuliandev, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly enhances the robustness and flexibility of the OpenFeature API by integrating cancellation token support into the provider initialization and error handling mechanisms. This refactoring allows for more controlled and responsive management of asynchronous operations during provider setup, improving the overall stability and resource management of the system.

Highlights

• Cancellation Token Integration: Introduced CancellationToken support into provider initialization and error handling functions across the OpenFeature API and repository.
• Delegate Signature Updates: Modified delegate signatures for afterInitSuccess and afterInitError callbacks to consistently accept a CancellationToken parameter.
• API and Repository Refactoring: Updated Api.cs and ProviderRepository.cs to pass CancellationToken through relevant calls, ensuring propagation throughout the initialization flow.
• Enhanced Test Coverage: Added new unit tests and updated existing ones in ProviderRepositoryTests.cs to verify the correct handling and propagation of CancellationToken in both successful initialization and error scenarios for default and named providers.

Code Review

This pull request successfully refactors the provider initialization logic to propagate cancellation tokens through internal methods and callbacks, which is a great improvement for robustness. However, the public-facing SetProviderAsync methods in the Api class have not been updated to accept a CancellationToken. This oversight prevents consumers of the API from actually using the new cancellation feature. I've left comments with suggestions on how to expose this functionality. I also found a minor typo in a new test method name.
