llama.cpp Adds DeepSeek V4 Flash Chat Template Support

Build b10254 of llama.cpp introduces official chat template support for DeepSeek V4 Flash, aligning with the official model specifications while providing flexible thinking token handling. The template properly manages DeepSeek V4's distinctive reasoning chain output, allowing practitioners to preserve or drop thinking tokens from conversation history as needed.

This update is critical because proper chat templates ensure models behave correctly during local inference—incorrect formatting can degrade output quality and waste tokens on reasoning. With first-class DeepSeek V4 support in llama.cpp, local practitioners can now deploy this advanced reasoning model with confidence that prompting and response parsing will work as expected.
