* 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.
The MLX runner is the only Go inference runner left and is no longer
experimental, so its packages leave x/. The bindings become a top-level
mlx package beside the carried patches in mlx/compat, mirroring how
llama/ holds the llama.cpp integration, and the runner becomes mlxrunner
with the architectures nested under the package they implement.
Subpackages move with their parent unless listed.

Every package keeps its name, so the Go changes are the import path
rewrites the moves force, and the CMake, Dockerfile, CI cache keys, drift
check and Darwin payload script follow the new paths. Four edits are not
paths: the runner's blank architecture imports become the package
mlxrunner/model/architectures, so the list to extend for a new model sits
beside the architecture directories; a depguard rule keeps the two test
harnesses out of non-test code, as the x/internal placement used to; the
CI change filter's two entries for the long-deleted x/imagegen/mlx now
name the bindings' CMake project and the carried patches, so a change to
either builds the payload; and the tokenizer parity test reads its
fixtures from its own testdata instead of walking out of x/.
x/server and x/imagegen/manifest stay for the next two commits.
