//! LLM provider trait, streaming primitives, and first-party provider implementations.
//!
//! This crate defines the [`LlmProvider`] trait that all LLM backends implement,
//! streaming types for incremental response processing, attachment validation,
//! model capability metadata, and seven first-party provider implementations.
//!
//! # Provider Implementations
//!
//! | Provider | Module | Protocol |
//! |----------|--------|----------|
//! | Anthropic (Messages API) | [`impls::anthropic`] | SSE streaming |
//! | OpenAI (Chat Completions) | [`impls::openai`] | SSE streaming |
//! | OpenAI (Responses API) | [`impls::openai_responses`] | SSE streaming |
//! | OpenAI Codex / ChatGPT | [`impls::openai_codex_responses`] | WebSocket |
//! | Google Gemini | [`impls::gemini`] | SSE streaming |
//! | Google Vertex AI | [`impls::vertex`] | SSE streaming |
//! | Cloudflare AI Gateway | [`impls::cloudflare_ai_gateway`] | Proxy wrapper |

#![forbid(unsafe_code)]

// The attachment-validation helpers are only ever called from a provider
// impl (each gated behind its provider feature), so the whole module is dead
// code when no provider is compiled in. Gate it on "any provider feature" to
// keep `--no-default-features` builds warning- (and `-D warnings`-) clean.
