feat: add parallel distance matrix computation for bit and int matrices

Introduce parallel distance matrix generation using `ndarray` and `rayon` for both `BitMatrix` and `IntMatrix`. Adds full and additive-partial variants for Jaccard, Hamming, Bray-Curtis, Euclidean, and Hellinger metrics. Includes comprehensive unit tests verifying matrix symmetry, zero diagonals, and numerical correctness against pairwise calculations.
