Crate descartes_metrics 

Metrics collection and observability for simulations

This crate provides comprehensive metrics collection, statistical analysis, and structured logging capabilities for simulation observability.

The crate leverages the standard Rust metrics ecosystem while adding simulation-specific functionality like request tracking and high-resolution latency analysis.
