Zeus 2× Arc Pro B70: llama.cpp SYCL FP16 tuning across Qwen3.8 and nine other model routes

Qwen3.8-27B-GGUF

On two Intel Arc Pro B70s, a b11190 SYCL FP16 build substantially improved prompt processing across 10 production routes. This report gives matched serving results, copy-heavy generation gains from n-gram drafting, rejected tuning variants, and measurement limits.
