//! Provider op implementations — LLMOp, EmbeddingOp, RerankOp, OnnxOp, TritonOp, PromptOp.
//!
//! Mirrors Python `operonx/providers/ops/` one-for-one. Python's `chain.py`
//! is authoring-layer (builds a GraphOp from `@graph`-decorated helpers);
//! the Rust port ships [`chain::build_chat_graph`] / [`chain::build_ask_graph`]
//! that emit the same serialized JSON shape for Rust-native callers — see
//! [`chain`] for the rationale.
