Mathias Beaulieu-Duncan a60f92c56d Add feature flag to switch between HTTP and gRPC transports ... Adds ApiModeConfig class with support for selecting API transport mode: - ApiMode enum (http, grpc) - Static configurations: development (HTTP), developmentGrpc, production, productionGrpc - fallbackToHttpOnError option for graceful degradation Creates unified deliveryRoutesProvider and deliveriesProvider that: - Respect apiModeConfigProvider for transport selection - Automatically delegate to gRPC or HTTP providers - Fall back to HTTP on gRPC failures when configured To enable gRPC, override apiModeConfigProvider with ApiModeConfig.developmentGrpc in the ProviderScope.
