Implement SHA-2 hash functions: SHA-256, SHA-384, SHA-512 master

Add pure Rust implementations of the SHA-2 family per FIPS 180-4 in the crypto crate: - SHA-256: 256-bit digest, 64-byte blocks, 64 rounds - SHA-512: 512-bit digest, 128-byte blocks, 80 rounds - SHA-384: truncated SHA-512 with different initial values All three provide streaming (new/update/finalize) and one-shot APIs. 21 tests including NIST test vectors (empty, abc, 448-bit, 896-bit, million-a) plus streaming and edge-case coverage.
