//! Harmony pipeline implementation
//!
//! This module provides support for GPT-OSS models that use Harmony encoding/parsing.
//! The Harmony protocol uses a channel-based approach with three channels:
//! - **analysis**: Reasoning/thinking content (optional)
//! - **commentary**: Tool calls (optional)
//! - **final**: Final response text (required)
//!
//! ## Architecture
//!
//! The Harmony implementation is structured as follows:
//!
//! - **detector**: Model detection (is this a Harmony-capable model?)
//! - **builder**: Request encoding (convert Chat/Responses → input_ids)
//! - **parser**: Response parsing (output_ids → channels)
//! - **types**: Shared type definitions
//!
//! ## Usage
//!
//! ```ignore
//! use sglang_router_rs::routers::grpc::harmony::{HarmonyDetector, HarmonyBuilder};
//!
//! // Detect if model supports Harmony
//! if HarmonyDetector::is_harmony_model("gpt-4o") {
//!     // Build Harmony request
//!     let builder = HarmonyBuilder::new();
//!     let output = builder.build_from_chat(&request)?;
//!     // ... use output.input_ids for gRPC request
//! }
//! ```
