+//! SAL Kubernetes: Kubernetes cluster management and operations
+//!
+//! This package provides Kubernetes cluster management functionality including:
+//! - Namespace-scoped resource management via KubernetesManager
+//! - Pod listing and management
+//! - Resource deletion with PCRE pattern matching
+//! - Namespace creation and management
+//! - Support for various Kubernetes resources (pods, services, deployments, etc.)
+//!
+//! # Example
+//!
+//! ```rust
+//! use sal_kubernetes::KubernetesManager;
+//!
+//! #[tokio::main]
+//! async fn main() -> Result<(), Box<dyn std::error::Error>> {
+//!     // Create a manager for the "default" namespace
+//!     let km = KubernetesManager::new("default").await?;
+//!     
+//!     // List all pods in the namespace
+//!     let pods = km.pods_list().await?;
+//!     println!("Found {} pods", pods.len());
+//!     
+//!     // Create a namespace (idempotent)
+//!     km.namespace_create("my-namespace").await?;
+//!     
+//!     // Delete resources matching a pattern
+//!     km.delete("test-.*").await?;
+//!     
+//!     Ok(())
+//! }
+//! ```
