Commit Message

Further optimize gost compress: uint64 key gen, unrolled encrypt

Rewrite gostCompress to use [4]uint64 for all 256-bit values (u, v, w),
eliminating byte-level xor32/xor32Bytes/gostTransformA. The key schedule
now produces [8]uint32 directly from uint64 words via byte extraction,
skipping the intermediate [32]byte + separate key loading step.

gostEncrypt is unrolled: the 3 forward passes and 1 reverse pass use
explicit key indices instead of k[i%8] and a reverse loop.

gost 64 KiB: 64 → 72 MB/s (+12%). Total from original: 13 → 72 MB/s (5.5x).
