Explains how to extract W3C trace context from ctx.request().attemptHeaders and propagate it to child spans and outbound calls. Also explains why Node.js auto-instrumentation cannot substitute for manual extraction: Restate wraps the HTTP layer and handlers replay, so per-attempt instrumentation would produce duplicate spans.
