//! Monitoring system for SV2 applications.
//!
//! Provides HTTP JSON API and Prometheus metrics for monitoring.
//! Read-only - does not modify any state.
//!
//! ## Architecture
//!
//! - **Server**: The upstream connection (pool, JDS) - typically one per app
//! - **Clients**: Downstream connections (miners) - multiple per app
//! - **SV1 clients**: Legacy SV1 connections (Translator only)
