//! Unified metrics collection for Vectorless.
//!
//! This module provides centralized metrics collection across all components:
//! - **LLM Metrics** — Token usage, latency, cost
//! - **Pilot Metrics** — Decisions, accuracy, feedback
//! - **Retrieval Metrics** — Paths, scores, iterations, cache
//!
//! # Architecture

//!
//! let config = MetricsConfig::default();
//! let hub = MetricsHub::new(config);
//!
//! // Record LLM call
//! hub.record_llm_call(100, 50, 150, true);
//!
//! // Record Pilot decision
//! hub.record_pilot_decision(0.85, InterventionPoint::Fork);
//!
//! // Generate report
//! let report = hub.generate_report();
//! println!("Total cost: ${:.4}", report.llm.estimated_cost_usd);
