flushOTel
▸ flushOTel():Promise<void>
Force-flush any GenAI spans buffered by the active span processor.
Resolves immediately if weave.init() has not been called. Otherwise
delegates to BasicTracerProvider.forceFlush(), which waits for the
underlying span processor to drain its queue and complete its OTLP export
round-trip.
Call before process exit when using 'simple' or any other processor that
may have in-flight work, or in tests that need to observe exported spans
synchronously.
Returns
Promise<void>
