@wpkernel/core / WPKernelEventBus
Class: WPKernelEventBus
Typed event bus used across WPKernel to broadcast lifecycle events and cache invalidation notices.
The bus automatically resolves a reporter so listener failures can be logged during development while remaining silent in production or when reporters are muted.
