//! MiniMax provider (reuses Anthropic Messages protocol).
//!
//! MiniMax exposes an Anthropic-compatible API endpoint at:
//! - `https://api.minimax.io/anthropic` (international)
//! - `https://api.minimaxi.com/anthropic` (minimax-cn, China mainland)
//!
//! This provider delegates all streaming to `AnthropicProtocol`.
//!
//! Note: MiniMax has a dual env var for API key resolution based on
//! the provider variant (MiniMax vs MiniMaxCN), which requires a
//! custom `resolve_api_key` instead of using the delegation macro.
