Move the event emitter and lifecycle events from the engine into the reducer, making the reducer the single point of orchestration for reduction. This eliminates the engine package entirely. - Add events.go to pkg/reducer with Start, Step, and Stop events. - Extend Reducer interface to embed Emitter and add Expression() method. - Update NormalOrderReducer to embed BaseEmitter and emit lifecycle events. - Update all plugins to attach to Reducer instead of Engine. - Remove internal/engine package. - Add Off() method to BaseEmitter to complete Emitter interface. - Fix Emitter.On signature to use generic type E instead of string.
