Walkthrough

A pre-check was added to the endpoint health check logic in internal/health/checker.go. The modification calls valkeyClient.GetRateLimitState(ctx, chain, endpointID) to query the rate-limit status of an endpoint. If the endpoint is rate-limited, a debug message is logged and the function returns early, bypassing the remaining health verification logic for that endpoint. This change adds 7 lines of code to implement the early return mechanism.
