xz-provider 0.5.0

//! LLM provider implementations.
//!
//! The only HTTP client implementation is [`GenericProvider`], which delegates
//! protocol encoding/decoding to a [`crate::protocol::ProtocolAdapter`].
//! Historical `OpenAiCompatibleProvider` (a second full HTTP stack) was removed;
//! OpenAI-compatible endpoints use `GenericProvider` + `OpenAiChatAdapter` /
//! `OpenAiResponsesAdapter` via [`crate::ProviderBuilder`].
