This implementation adds intelligent interruption handling to distinguish between backchanneling and active interruptions.

Features

✅ Backchannel Detection: Ignores "yeah", "ok", "hmm" when agent is speaking
✅ State Awareness: Same words processed differently based on agent state
✅ Semantic Interruption: Detects interrupt words in mixed sentences
✅ No Pausing: Agent continues seamlessly without stuttering
✅ Configurable: Easy to customize word lists
