Module trace_context 

W3C Trace Context propagation for distributed tracing. W3C Trace Context propagation for distributed tracing.

The GitHub Copilot CLI propagates W3C Trace Context headers (traceparent and tracestate) so SDK consumers can correlate spans created by the CLI with their own observability pipelines.

Two injection paths are supported:

• Per-turn override via MessageOptions::traceparent / MessageOptions::tracestate, which take precedence when set.
• Ambient callback via ClientOptions::on_get_trace_context, which the SDK invokes before session.create, session.resume, and session.send whenever the per-turn override is absent.
