Type-safe event handler system with versioning, telemetry, and contract validation for distributed Arvo event-driven architectures, featuring routing and multi-handler support.

 * 1. Ensures all service contracts have unique URIs (no duplicate contracts)
 * 2. Prevents circular dependencies (self contract not registered as service)
 *
 * These validations prevent configuration errors that would cause runtime
 * failures or infinite execution loops in orchestration workflows.
