//! Metric collection subsystem: watches the engine's metric registry, samples it on a cadence, and delivers
//! snapshots to whatever sink the deployment has configured (an in-process listener, a periodic logger, an external
//! exporter via the OTel subsystem). Interceptors hook into individual metric updates so a sink can react to events
//! rather than poll.
//!
//! The crate produces no metrics of its own; the engine's `metric/` crate is the source. This subsystem only owns
//! the delivery path. New sinks plug in as listeners; new metric kinds belong in `metric/`.
