Wire a service's OpenTelemetry output to Sematext Cloud. Walks through region, App-type, instrumentation flow (managed OTLP endpoint vs Sematext Agent), and signal selection (traces/metrics/logs), then produces the exact env-var block and points at a runnable reference example in this repo. Invoke when instrumenting a new app for Sematext.
