Adds gcp_cloud_run/: a long-running Temporal worker for Google Cloud Run worker pools that uses the temporalio.contrib.gcp.cloud_run OpenTelemetryPlugin to export Core metrics and traces over OTLP/gRPC to a local OpenTelemetry Collector sidecar (worker, workflow, starter, collector-config.yaml, worker-pool.yaml, Dockerfile, README). Note: the cloud-run-worker-otel SDK extra is not yet released, so pyproject.toml temporarily uses an editable local path source to resolve temporalio against a sibling sdk-python checkout. Replace it with a released temporalio[cloud-run-worker-otel] and regenerate uv.lock before this is marked ready.

Make TEMPORAL_API_KEY optional and enable TLS only when an API key is present, so the sample connects to a plaintext dev server or self-hosted cluster, not just Temporal Cloud (matches the Go and Java samples). Verified by deploying to Cloud Run against a dev server. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
