{"agent":"claude","input":"Add OpenTelemetry tracing to this NestJS service. Read src/main.ts, src/app.module.ts, one of the src/*/config/*.config.ts files, env-example-relational, env-example-document and docker-compose.yaml first. Add src/instrumentation.ts with the Node SDK, auto-instrumentations for http, express, pg, mongoose and @nestjs/core, and an OTLP HTTP exporter configured by OTEL_SERVICE_NAME and OTEL_EXPORTER_OTLP_ENDPOINT; import it first in src/main.ts and flush on shutdown. Add both variables to the two env-example files. Add an otel-collector service with a debug exporter to docker-compose.yaml, start the stack, make a login and a users request, and keep the collector output showing the request, handler and database spans. Add a Jest test with an InMemorySpanExporter. Do not touch entity files or generators. Run npm run lint, npm run test and npm run build, and open a pull request with the span output.","resources":[{"url":"https://github.com/your-org/your-app"}]}
