//! 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
