Create Standalone KubeStellar CLI with Shared Core Functionality

Summary

Develop a standalone KubeStellar CLI (kubestellar) that provides the same multi-cluster management capabilities as the kubectl plugin (kubectl-multi), with shared core functionality between both implementations to avoid code duplication and ensure feature parity.

Background

Currently, KubeStellar provides multi-cluster management through a kubectl plugin (kubectl-multi). While this works well for users familiar with kubectl, there's a need for a standalone CLI that:

• Can be used independently without kubectl
• Provides a dedicated KubeStellar-branded experience
• Shares the same core functionality to maintain consistency
• Reduces maintenance overhead through code reuse
