* MLX, MLX-C: version bump

The MLX-C pin now provides its own bindings for gather_qmm global_scale
and fast::gated_delta_update, so those two carried patches drop out.
Carry 0001-mlx-c-sdpa-window-size instead: sliding-window attention
added a window_size argument to fast::scaled_dot_product_attention
(ml-explore/mlx#4734) that MLX-C has not bound yet, to be regenerated
from MLX-C once the upstream binding PR merges. The SDPA wrappers gain
a window size argument; all call sites default to the full context.

* mlxrunner: dispatch sliding-window prefills to the native SDPA window

Sliding layers no longer materialize a causal∩sliding mask for prefill
chunks past the window: resolve() dispatches {causal, window} natively
when the rotating cache's L>1 concat has linearized the ring and the
mask is otherwise pure causal, via a new MaskApplier.NativeWindow hint.
Vision relaxations, padding, model arrays, and decode keep the
materialized path. No model changes; sinks compose natively.
