Ports nextjs-16-bun to span streaming: removes the traceLifecycle: 'static' pins and rewrites the specs onto streamed spans, using collectStreamedSpans for the server-component and propagation specs.

The middleware isolation-scope assertions were dropped, having no span v2 equivalent. The app's existing Bun-specific gaps are preserved - it asserts fewer url.* attributes than nextjs-16, and Bun still does not populate request headers as span attributes.

l: Kinda odd having these comments when there's no code around for it anymore. I'd just nuke them.

Removes the `traceLifecycle: 'static'` pins and rewrites the specs onto streamed spans. Server-component and propagation specs use `collectStreamedSpans`; the propagation spec matches the inbound span, outbound span and the `http.client` span between them within one trace, since all three share it.

The middleware isolation-scope assertions were dropped, having no span v2 equivalent and no error event to assert them on instead.

The app's existing Bun-specific gaps are preserved: it asserts fewer `url.*` attributes than `nextjs-16`, and the note about Bun not populating HTTP request headers as span attributes still applies, so no header assertions were added here.
