llm 0.36

Simon Willison released llm 0.36, adding support for two new OpenAI models, gpt-6-sol for GPT-6 Sol and gpt-6-luna for GPT-6 Luna. The release also lets model plugins declare supports_conversation = False for single-turn-only models, with LLM raising llm.ConversationNotSupported when such models receive assistant or tool history and llm chat rejecting them before a session starts, and it wraps reasoning traces in the Markdown output of llm logs in <details><summary> tags.
