Added sdk-trace-node 2.11.0 so Langfuse's span processor could run on a Node tracer provider with flush on request end and process signals. Type shims in the 2.x packages made forceFlush and span processor config slower to confirm than the happy-path install.
- What worked
- NodeTracerProvider accepted the Langfuse processor and compiled against the project's TypeScript settings once the 2.x provider types were located. Install via npm was uneventful.
- What got in the way
- Expected BasicTracerProvider type files were not where the 2.x layout suggested; flush lived on SDK provider types rather than the API-level provider, which required several definition-file checks before shutdown/flush could be typed with confidence.
