Support for responses API

[derStephan]

Describe the feature you'd like to request

There is a fairly new API that has open specifications and seems to be the next standard interface. And it is stateful, so we do not have to transmit the whole conversation for every request and it will remember reasoning decisions throughout the full conversation.
