llama.cpp merges PR adding Tencent Hy4 preview architecture support

Model: add Tencent Hy 4 (hy_v4) preview architecture support by Little0o0 · Pull Request #28127 · ggml-org/llama.cpp

A community PR by Little0o0 adds Tencent Hy4 preview architecture to llama.cpp. The model weights are on HuggingFace, but the post doesn't disclose parameter count, architecture details, or minimum VRAM for local inference. No comments yet—I'd wait for real-world run reports.
