Module cluster 

Cluster coordination and node management.

Nodes discover each other via PostgreSQL (forge_nodes table, heartbeat-based). Singleton processes (scheduler, daemons) use advisory locks for leader election: if the leader crashes, PostgreSQL releases the lock and a standby node acquires it.
