Breaking: conversations now go through the Home Assistant chat API, so tool results, cards and follow-up turns behave the way the built-in agents do. Configuration is simplified: the system prompt is rendered once per conversation, the conversation is trimmed to the model context automatically, sampling parameters left empty are left to the server, and the GBNF grammar is typed in instead of loaded from a file. The text-generation-webui backend has been removed. Models that used it are switched to the OpenAI compatible API and a repair issue lists the settings that could not be carried over.
