feat: reorganize examples and add signature support to JobBuilder
- Reorganized examples into osiris/, sal/, and utils/ folders - Moved hardcoded scripts to separate .rhai files - Added signature() method to JobBuilder for job signing - Updated OSIRIS context to use block_in_place instead of runtime - Removed runtime field from OsirisContext - Added typed save() methods for Note and Event objects - Updated all examples to use new structure and APIs

//! Multi-namespace Kubernetes operations example
|
||||
//!
|
||||
//! This script demonstrates working with multiple namespaces and comparing resources across them.
|
||||
//!
|
||||
//! Prerequisites:
|
||||
//! - A running Kubernetes cluster
|
||||
//! - Valid kubeconfig file or in-cluster configuration
|
||||
//! - Appropriate permissions for the operations
|
||||
//!
|
||||
//! Usage:
|
||||
//! herodo examples/kubernetes/multi_namespace_operations.rhai
