Module seed 

BIP-39 mnemonic and deterministic key derivation for void identities.

This module provides:

• 24-word BIP-39 mnemonic generation
• Mnemonic → seed conversion
• HKDF-SHA256 derivation of signing and recipient keys from a seed

The derivation uses domain-separated HKDF so that the same seed produces distinct, deterministic Ed25519 signing and X25519 recipient keys.

Enums

SeedError

Errors during seed/mnemonic operations.

Functions

derive_nostr_key
