//! # Training Module
//!
//! This module provides training data generation and fine-tuning utilities
//! for RuvLTRA models, including Claude Flow task datasets and MCP tool training.
//!
//! ## Submodules
//!
//! - [`claude_dataset`]: Task routing dataset generation
//! - [`grpo`]: GRPO (Group Relative Policy Optimization) for RL
//! - [`tool_dataset`]: MCP tool calling dataset generation (140+ tools)
//! - [`mcp_tools`]: MCP tool trainer with GRPO-based fine-tuning
//!
//! ## Example: Tool Use Fine-Tuning
//!
//! ```rust,ignore
//! use ruvllm::training::{McpToolTrainer, McpTrainingConfig, ToolDatasetConfig};
//!
//! // Create trainer
//! let config = McpTrainingConfig::default();
//! let mut trainer = McpToolTrainer::new(config)?;
//! trainer.load_tool_definitions()?;
//!
//! // Generate training data
//! let dataset = trainer.generate_tool_dataset(ToolDatasetConfig::comprehensive())?;
//! println!("Generated {} examples", dataset.len());
//!
//! // Evaluate baseline
//! let metrics = trainer.evaluate_tool_accuracy(&dataset.examples)?;
//! println!("Baseline accuracy: {:.2}%", metrics.tool_accuracy * 100.0);
//! ```
