Module hash 

Hardware-accelerated hashing with SIMD support

This module provides a pluggable hash algorithm system with:

• Runtime CPU feature detection
• SIMD-optimized implementations (AVX2 for x86_64, NEON for ARM)
• Fallback to standard implementations
• Modern hash algorithms (BLAKE3)

Example

use ipfrs_core::hash::{HashEngine, Sha256Engine, Sha512Engine, Blake3Engine};

let data = b"hello world";

// SHA2-256 (32 bytes)
let sha256 = Sha256Engine::new();
let hash256 = sha256.digest(data);

// SHA2-512 (64 bytes) - stronger security
let sha512 = Sha512Engine::new();
let hash512 = sha512.digest(data);

// BLAKE3 is fastest with built-in SIMD
let blake3 = Blake3Engine::new();
let blake3_hash = blake3.digest(data);
