Conversation
The AI provider skip registry was a module-global Set that the Node and Cloudflare clients cleared once per client. Skips are registered lazily by higher-level integrations at call time (LangChain marking its providers, Vercel AI marking Workers AI), so a single such call suppressed the spans of direct provider calls in every later request served by the same client: for the whole process on Node, for the whole isolate on Cloudflare. The registry is now keyed on the isolation scope. A skip registered inside an invocation applies to that invocation only, one registered outside any invocation still applies everywhere. The per-client clear in the Node and Cloudflare clients is no longer needed. Adds a Node integration test that sends a LangChain request followed by a direct Anthropic request on one server and asserts the second one keeps its span.
