Laguna S 2.1 Thinking mode

If many people have noticed that there's no reasoning phase in Laguna S 2.1. I noticed the Poolside development team updated the chat template twice in the last 24 hours. There was a bug where, if preserve_thinking was disabled, reasoning wouldn't start at all.

However, I don't think that's the root cause. Could you take a look at the Qwen 27B chat template? It enables reasoning correctly for the Laguna S 2.1 model when used with the --chat-template-file parameter in llama.cpp.

I hope this information helps you track down and fix the template issue.
