EventTracer

Collects PHPUnit events grouped by their concrete event class.

This tracer MUST store every received event instance under its fully qualified class name so tests MAY later inspect which events were emitted and how many times each event type occurred during execution.

The collected events SHALL remain available in memory for the lifetime of this tracer instance. Consumers SHOULD treat the stored event collection as test-support state and SHOULD NOT rely on it for production behavior.
