Introduce a fork digest mechanism that enables nodes to identify compatible peers during network upgrades via the handshake and Hive peer gossip. Key features: - 4-byte fork digest derived from genesis hash and fork version - Handshake integration for connection-time compatibility checks - Hive protocol integration for fork-aware peer gossip filtering - Updated BzzAddress signature scheme (v1) removing redundant prefix - Two-release migration path for backwards compatibility
