static <I, O> Middleware<I,O>	CommonMiddleware.timeout(long timeoutMs)	Creates a timeout middleware that throws an exception if execution takes too long.
static <I, O> Middleware<I,O>	CommonMiddleware.timing(Consumer<Long> callback)	Creates a timing middleware that measures execution time.
static <I, O> Middleware<I,O>	CommonMiddleware.transformRequest(Function<I,I> transformer)	Creates a transformation middleware that transforms the request before processing.
static <I, O> Middleware<I,O>	CommonMiddleware.transformResponse(Function<O,O> transformer)	Creates a transformation middleware that transforms the response after processing.
static <I, O> Middleware<I,O>	CommonMiddleware.validate(Consumer<I> validator)	Creates a validation middleware that validates the request before processing.
