- Update health check messages in CI workflows to specify HTTP and gRPC readiness for the Tai service.
- Refactor integration tests to use `require` assertions instead of `assert`, improving error handling and test reliability.
- Ensure that responses from gRPC calls are not nil, enhancing test robustness.
These changes improve the clarity of service readiness checks and strengthen the integration test suite.
- Mark Phase 4 and Phase 5 as complete, indicating successful removal of fixed upstream connections and the introduction of dynamic routing based on request metadata.
- Implement `TokenManager` for handling authentication tokens and update gRPC client methods to support new features.
- Enhance tests for dynamic routing and token management, achieving significant coverage improvements.
- Begin preparations for Phase 6, outlining the structure for OAuth Device Flow and related tasks.
This commit finalizes key gRPC features and sets the stage for upcoming authentication enhancements.
