Enum MetricKind 

pub enum MetricKind {
    Counter {
        total: f64,
        reset_detected: bool,
    },
    Gauge {
        value: f64,
    },
    Histogram {
        count: u64,
        sum: f64,
        p50: Option<f64>,
        p95: Option<f64>,
        p99: Option<f64>,
    },
}

Metric semantics matter: counters reset, gauges fluctuate, histograms sample.
