Removes the `traceLifecycle: 'static'` pin from the twelve `suites/tracing/propagation` suites, and rewrites the assertions from transaction envelopes to span v2. Each hop of a propagated trace runs in its own isolate and streams its own envelope, so a suite reads one segment span per envelope and then checks `trace_id` and `parent_span_id` between them. Most suites keep one envelope expectation per hop with `.unordered()`, which stays close to the shape they had. `worker-service-binding` uses `collectStreamedSpans` instead, because it only needs the two segment spans of one trace. Every route in these suites is a raw URL, so the streamed segment name keeps the method only. `GET /chain` becomes `GET`, and the route is read from the `url.path` attribute. The `sed` that removed the pins took a whole line with it in `worker-workerentrypoint-rpc/index.ts`, where the options callback sat on one line. This restores `LoopbackEntrypoint` with its `tracesSampleRate: 0`. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
