Module telemetry 

Telemetry: lifecycle callbacks, options and the built-in tracing spans.

Lifecycle callbacks are awaited concurrently and isolate unwinding panics. The two execute_* wrappers preserve the actual call result. Integrations are injected per call through TelemetryOptions::integrations; there is no global registry. Callback settlement and wrapper ordering follow the Vercel AI SDK (packages/ai/src/telemetry/create-telemetry-dispatcher.ts); see NOTICE.
