//! [`AgentFactoryPort`] — materialize an [`AgentPort`] from a typed
//! descriptor.
//!
//! Callers (the composition root and the `RegisterAgent` RPC) do not
//! construct agent implementations directly; they hand a descriptor to
//! this factory and receive a live handle back. That keeps the set of
//! wired providers (vLLM, Anthropic, OpenAI, rule-based, human-in-the-
//! loop, …) behind Cargo features at the adapter layer, exactly like
//! every other provider-specific concern in this crate.
//!
//! The `kind` field in [`AgentDescriptor`] names the provider the
//! factory should dispatch to. Adapters return
//! [`DomainError::InvariantViolated`] when asked for a kind they do
//! not support; the composition root is responsible for wiring a
//! factory that recognises every kind the deployment intends to accept.
