// Agent identity domain types
//
// Design Decision:
// - AgentIdentity is a first-class virtual principal, separate from Agent behavior.
// - It carries durable presentation + preference defaults and can be bound to Apps
//   and Sessions without implying every interactive turn acts as the identity.
