Distributed Sagas, Locking, and Zero-Config Documentation in NodeJS

HazelJS v0.4.0 introduces @hazeljs/saga for declarative distributed transactions supporting both orchestration and choreography patterns with auto-compensation, and @hazeljs/distributed-lock for mutual exclusion across multi-node environments using Redis or in-memory backends. Both packages feature decorator-based APIs, type-safe context, and automatic cleanup, along with observability and developer productivity improvements across the 45+ package ecosystem.
