//! Protocol-driven provider-client factory.
//!
//! A provider client is selected by the registry entry's [`WireProtocol`], not
//! by its name: any vendor speaking `anthropic` reuses [`AnthropicProvider`],
//! any speaking `openai-chat`/`openai-responses` reuses [`OpenAiProvider`], and
//! `gemini` uses [`GeminiProvider`]. Connectivity (endpoint, resolved key)
//! comes from the profile `providers` registry; the per-provider AI policy
//! supplies resilience and the web-search toggle.
