Enable a new model architecture/family in the OpenVINO GGUF frontend's native .gguf builder, or check whether a GGUF model is supported. Use when the user asks to enable, support or bring up a GGUF/llama.cpp model (llama, qwen, phi, gemma, MoE and similar decoder-only families), when a .gguf file is rejected as an unsupported architecture, or when working on arch_registry / DecoderBuilder in src/frontends/gguf/src/builder/. Do NOT use for adding a single ggml op translator or for debugging wrong output from an already-supported model.
