Update llama.cpp to support newer Quen (3) models.

Getting and errror when trying to run Qwen 3 model, Following same approach as readme instructions.

Most models have a slightly different architecture which require llama.cpp to be updated. Depending on how new the model is, llama.cpp may require updating. If llama.cpp didn’t make breaking changes all the time, I would just publish a new build of the native library regularly.
