Add non-blocking pod log streaming example

[Sakku4590]

This PR adds a non-blocking example for streaming pod logs using socket timeouts, allowing graceful shutdown without indefinite blocking.

The existing pod_logs.py example blocks when no new logs arrive. This new example demonstrates a safe streaming pattern tested against a live Kubernetes cluster (Minikube).

Fixes #2474
