feat: Port RustChain miner to Rust (#1601)

[ma-moon]

RustChain Miner - Native Rust Implementation

🦀 Port of rustchain_universal_miner.py to native Rust.

Features Implemented

• ✅ Hardware Detection - CPU, memory, platform fingerprinting
• ✅ Ed25519 Attestation - Cryptographic signing for miner identity
• ✅ Anti-Emulation Checks - Detects common VM/emulator indicators
• ✅ Cross-Platform - Linux, macOS, Windows support
• ✅ Configurable - TOML-based configuration
• ✅ Async Runtime - Built on Tokio for high performance
