Description

All titles in the chat history show up as: <think>Okay, the user wants ...

I suppose the auto title code hasn't been updated to handle models that begin with a <think> block? So either split out or append /no_think to the prompt.

To reproduce

1. Use a think-based model like qwen3.
2. Start a chat.
3. Check the history and see the unhelpful title.
