Struct DeepSeekTemplate 

pub struct DeepSeekTemplate;

DeepSeek-LLM chat template.

<｜begin▁of▁sentence｜>{system}

User: {user}

Assistant: {assistant}<｜end▁of▁sentence｜>

The system prompt is emitted bare (no role marker) after the BOS token, then turns alternate User: / Assistant:. (DeepSeek-Coder uses an Alpaca-style ### Instruction: format instead and resolves to AlpacaTemplate.)
