Enum ObserverMetric 

pub enum ObserverMetric {
    RequestLatency(Duration),
    TokensUsed(u64),
    ActiveSessions(u64),
    QueueDepth(u64),
}

Numeric metrics emitted by the agent runtime.

Observers can aggregate these into dashboards, alerts, or structured logs. Each variant carries a single scalar value with implicit units.
