Introduction to Event Engine Daemon

@sullux/event-engine-daemon provides process management, supervisor event loops, and plugin lifecycle orchestration for @sullux/event-engine.

In a distributed or edge deployment, plugins (such as email pollers, file chunk listeners, and cron schedulers) run inside long-lived daemon background processes. @sullux/event-engine-daemon makes this process lifecycle completely event-sourced: every startup request, successful initialization, plugin crash, and shutdown signal is captured as an immutable event in the engine ledger.

Key Features

• Event-Sourced Supervision: Process and plugin state transitions are recorded as daemon.start.requested, daemon.plugin.started, daemon.plugin.failed, and daemon.stopped.
• Graceful Signal Handling: Traps SIGINT, SIGTERM, and SIGHUP to cleanly flush transactional outbox queues before exiting.
• Fault Isolation: Uncaught exceptions in plugin event loops emit failure events and trigger isolation or restart policies without corrupting SQLite state.
• CLI & Service Management: Ready to run as a systemd unit or containerized daemon.
