Go GC cannot see Metal/C memory pressure, so intermediate arrays from
each forward pass accumulated without bound, causing OOM kills after
3-4 requests. Fix: runtime.SetFinalizer on every Array releases C
handles when GC collects them, and runtime.GC() is forced every 4
tokens during generation. Also adds SetMemoryLimit(24GB) as a hard
Metal ceiling.

CGo wrapper for mlx-c providing zero-Python Metal GPU inference.
Includes Gemma 3 model architecture, BPE tokenizer, KV cache,
composable sampling, and OpenAI-compatible serve command.
Build-tagged (darwin && arm64 && mlx) with stubs for cross-platform.
