Adds cloud-run-worker/: a long-running Temporal worker for Google Cloud Run worker pools that uses the temporal-gcp-cloud-run CloudRunOpenTelemetryPlugin to export Core metrics and traces over OTLP/gRPC to a local OpenTelemetry Collector sidecar (worker, greeting workflow/activities, collector-config.yaml, worker-pool.yaml, Dockerfile, README). Note: the SDK module temporal-gcp-cloud-run is not yet released, so the sample resolves it via the existing -PtemporalSdkPath composite build against a local sdk-java checkout. Bump javaSDKVersion to the release that ships the module before this is marked ready. Co-authored-by: Edward Amsden <edward.amsden@temporal.io> Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
