//! Anthropic model listing.
//!
//! The [`AnthropicModelLister`] is defined in the parent module
//! (`anthropic/mod.rs`) alongside the client, because it shares
//! private constants (`ANTHROPIC_MODELS_URL`, `ANTHROPIC_VERSION`) and
//! the HTTP client plumbing.
//!
//! This file exists for structural consistency with other provider
//! directories that split models into their own submodule.
