Function traced

Wraps fn in a span named name, by convention layer.domain.method (repo.usuarios.buscar): the span is the active one while fn runs, so the spans started inside (a query, a call to another service) are its children; a throw or a rejection marks it as an error. Without an OpenTelemetry SDK it costs a no-op span.

const buscar = traced('repo.usuarios.buscar', async (id: number) => oracle.one(SQL, { id }));
