Fixture: agent-person-simple

Source: https://heratio.theahg.co.za/api/ric/v1/agents/d6mh-ktzy-h6qz

A single Agent response (in this case resolved as rico:Agent because the underlying actor has no entity_type_id). Exercises: @context prefix bindings, @id/type/name minimal Agent payload, schema selection by @type, SHACL AgentShape with rico:name shorthand.

Validation: expected.jsonld MUST validate against the schema selected by its @type.
