Ed25519HdWallet class

Pure Dart implementation of SLIP-0010 Ed25519 HD Wallet.

SLIP-0010 defines hierarchical deterministic key derivation for Ed25519. Unlike BIP-32, Ed25519 derivation:

• Only supports hardened derivation (all indices must be >= 2^31)
• Does not support public key derivation
• Uses the hash directly as private key (no addition with parent)

Supported derivation paths:

• Solana: m/44'/501'/0'/0'
• TON: m/44'/607'/0'
