German voice demos, now first-class

Voice demos now treat German as a first-class language, backed by an upgraded speech-recognition stack that makes conversations more accurate and natural, in German and English alike.

• Full German voice conversations: the agent can now listen and speak in German
• Sharper speech recognition: new multilingual recognition models understand visitors more accurately
• More natural turn-taking: the agent now does a better job deciding when a visitor has finished their thought rather than just waiting for a pause, so it interrupts less and replies faster
