Andrej Karpathy	3ba42e8135	Fix SDPA KV-cache decode to respect sliding window (#456) ... SDPA fallback now respects sliding window during single-token KV-cache decode by slicing K/V to the last (window + 1) tokens. Also simplifies the mask building for chunk inference to properly apply sliding window in that path as well.
