/**
 * LangSmith observability bridge for Nevermined payments (TypeScript).
 *
 * Surfaces the cross-SDK `nvm:verify` / `nvm:settlement` spans defined by the
 * observability-spans-v1 contract, matching the Python SDK attribute-for-
 * attribute so a single LangSmith trace can be correlated across both SDKs.
 *
 * These helpers are wired into the `requiresPayment` decorator automatically;
 * they are also exported here for manual use in non-LangChain code paths.
 *
 * Requires the optional `langsmith` peer dependency and `LANGSMITH_TRACING=true`;
 * every helper no-ops when tracing is inactive or `langsmith` is not installed.
