Signal<T extends Event> class

Lightweight wrapper around EventManager that mimics Django-like signals.

Handlers can connect and disconnect; when a signal dispatches, handlers are invoked sequentially. Registrations support optional de-duplication keys, sender scoping, and return a SignalSubscription for disposable lifecycle management. Exceptions are caught and re-published as UnhandledSignalError events for observability.
