+Fix DevToolsClient not flushing final span events on teardown.
+
+The stream consumer was `forkScoped`, causing it to be interrupted before
+it could drain remaining queue items. Replaced with `forkChild` and
+`Fiber.await` in the finalizer so the stream drains naturally after the
+queue is failed.
