Reduce interrupted audio playback events

Intermediate45 min

Implement replay_audio(events), a teaching reducer returning active, queued, and heard state for start, chunk, play, and interrupt events.

start sets a non-None response ID and clears unplayed queued chunks.
chunk appends text only when its response matches the active non-None response.
play moves up to count queued chunks to heard; reject negative count.
interrupt clears queued chunks and active response but preserves heard chunks. Reject unknown event types.

EXAMPLE 1

Inputstart r1; chunk hello; play 1; interrupt; late chunk r1

Output{'active': None, 'queued': [], 'heard': ['hello']}

Playback history survives; old response data cannot re-enter the queue.
