llama.cpp PR boosts prompt processing with vectorized F16-F32 conversion

A pull request to the llama.cpp project introduces vectorized conversion of F16 to F32 for Flash Attention V-Cache. This optimization leverages hardware F16C intrinsics, resulting in a significant performance boost. Specifically, it offers a 17-31% increase in prompt processing speed for smaller models like qwen3:4b. AI

IMPACT Improves inference speed for local LLM deployments by optimizing V-Cache conversion.

RANK_REASON This is a code optimization for a specific library, not a new model release or significant industry event.
