//! Lattice Core
//!
//! Core types for the Lattice distributed mesh:
//! - **Node**: Identity with Ed25519 keypair
//! - **SigChain**: Append-only cryptographically signed log
//! - **Entry**: Atomic operations in the log
//! - **VectorClock**: Causality tracking for reconciliation
//! - **HLC**: Hybrid Logical Clock for ordering
//! - **Clock**: Time abstraction for testability
//! - **Proto**: Generated protobuf types from lattice.proto
//! - **DataDir**: Platform-specific data directory paths
//! - **SignedEntry**: Entry creation, signing, and verification
//! - **Log**: Append-only log file I/O
