feat: Add Kubernetes module to SAL

- Add Kubernetes cluster management and operations
- Include pod, service, and deployment management
- Implement pattern-based resource deletion
- Support namespace creation and management
- Provide Rhai scripting wrappers for all functions
- Include production safety features (timeouts, retries, rate limiting)
