Browser realtime translation demo with OpenAI Realtime Translation (gpt-realtime-translate, gpt-realtime-whisper)

AI Impact Summary

Adds a browser-based, one-way real-time translation capability using OpenAI's Realtime Translation workflow. The demo wires a short-lived client secret from the server and uses WebRTC to stream tab audio to OpenAI models (gpt-realtime-translate and gpt-realtime-whisper) with on-page captions. This provides a concrete blueprint for integrating live translation and captions into web apps, but production deployments must address secret management, user consent for audio capture, and latency considerations.
