Add Frameless Bidi support for realtime conversations

What changed

  • Add realtime conversation version v3, which preserves the V1 Codex Voice behavior while using Frameless Bidi delegation.* events.
  • Translate audio, transcripts, handoffs, session context, and lifecycle events between the app server and the Frameless Bidi wire protocol.
  • Support v3 over WebSocket and WebRTC, including the Frameless /live endpoint, session configuration, headers, and default model selection.
  • Update the app-server protocol schemas and documentation for the new version.

Testing

  • Add unit coverage for Frameless event parsing, outbound messages, context chunking, URL construction, and call creation.
  • Add app-server end-to-end coverage for WebSocket delegation and WebRTC session startup.
