Detailed Description

Event-driven architecture infrastructure for decoupled component communication.

Provides a publish/subscribe event bus for decoupled communication between components without direct dependencies. Key features:

• Event Bus: In-process publish/subscribe with type-safe callbacks
• Event Traits: Type-to-name mapping for protocol integration
• Subscriptions: RAII-based subscription management with auto-unsubscribe
• PostgreSQL Events: LISTEN/NOTIFY bridge for database change notifications
• Entity Change Events: Domain-agnostic change notification with timestamps
• Thread Safety: All event bus operations are thread-safe

The domain namespace defines event types, traits, and entity change events. The service namespace provides the event_bus implementation and PostgreSQL integration via postgres_listener_service and postgres_event_source.
