Gust.Leader (gust v0.1.26)

Elects a single leader node and manages leader-only children.

The leader process attempts to acquire a distributed lock in the database. When the lock is held, the node becomes the leader and starts the configured leader-only workers under Gust.LeaderOnlySupervisor. If the lock is lost, the leader-only workers are terminated and the node returns to follower mode.
