Refactors the event emitter system from string-based messages to a type-safe generic implementation using typed events. Consolidates separate tracker packages into a unified plugins architecture. Changes: - Replace Emitter with BaseEmitter[E comparable] using generics - Add Event type with StartEvent, StepEvent, and StopEvent constants - Create Listener[E] interface with BaseListener implementation - Consolidate explanation, performance, and statistics trackers into internal/plugins package - Simplify main CLI by using plugin constructors instead of manual event subscription - Add Items() iterator method to Set for idiomatic range loops
