Contract reference definition with validation metadata.

This enum captures the validation parameters for contract reference types, enabling ABI consumers to understand what address or code ID a reference type validates against.

Uses compact addressing: - Instance: `contract` field with format "deployer\_entity::component\_index" - Implementation: `code_id` field with format "pusher\_entity::push\_index"

## JSON Format

Instance references serialize as: `json { "instance": { "component_code_name": "token-mock", "contract_instance_name": "alpha", "contract": "656e746974795f30...::1" } } `

Implementation references serialize as: `json { "implementation": { "component_code_name": "token-mock", "code_id": "656e746974795f30...::1" } } `
