llm: keep gemma3n projector off the CPU (#18376 )

Gemma3n's MobileNetV5 projector silently produces corrupted image embeddings on the CPU backend - no error, the model just describes the wrong image (reproduced on llama.cpp b10760; gemma4's encoder is fine on CPU). Without this guard the existing partial-offload, limited-VRAM, and OOM-retry fallbacks would pick the CPU projector on exactly the small GPUs where gemma3n lands.

+# Prepare MLX runtime libraries for macOS CI unit tests.
+#
+# Building MLX is expensive, so to enable the MLX-specific unit tests this
+# helper finds the newest Ollama release whose MLX_VERSION and MLX_C_VERSION
+# match the current checkout, downloads that release's ollama-darwin.tgz, and
+# extracts only mlx_metal_v* into build/lib/ollama.
+#
+# The payload also depends on Ollama's payload build rules (cmake glue and
+# carried mlx/compat patches) and the xgrammar native wrapper
+# (x/mlxrunner/xgrammar/native). Rule drift rebuilds the whole payload from
+# source; wrapper-only drift rebuilds just libollama_xgrammar.dylib.
+#
+# If no release matches the MLX pins (e.g. right after a pin bump), the
+# helper builds the minimal MLX payload for this platform: a single Metal
+# variant using the superbuild's platform default (metal_v4 on macOS 26.2+
+# SDKs, otherwise metal_v3), including a fresh libollama_xgrammar.dylib.
+# Built payloads are cached in the release tarball's layout for later runs.
