1. Error handler thread safety: last_mlx_error now uses _Atomic(const char*) with atomic_store_explicit/atomic_exchange_explicit (release/acquire). 2. macOS version minimum: -mmacosx-version-min changed from 26.0 to 13.3 (MLX's own minimum), no longer locks out macOS 14/15 users. 3. LoadOption applied in metalBackend.LoadModel(): calls ApplyLoadOpts(), passes ContextLen through to Model which replaces unbounded KVCache with RotatingKVCache when set. GPULayers=0 logs a warning.
