SIMD: Fix compile error by using MaxLanes instead of Lanes for array size

Replace hn::Lanes(f64) with hn::MaxLanes(f64) when defining the index array size to fix error C2131: "expression did not evaluate to a constant". This error occurs because Lanes() isn't always constexpr compatible, especially with scalable vector extensions. MaxLanes() provides a compile-time constant value suitable for static array allocation.
