1//! Cluster coordination and node management.
2//!
3//! Nodes discover each other via PostgreSQL (`forge_nodes` table, heartbeat-based).
4//! Singleton processes (scheduler, daemons) use advisory locks for leader election:
5//! if the leader crashes, PostgreSQL releases the lock and a standby node acquires it.
