MetricMetadata
A single metric observed on a context graph node.

- attributes

Per-metric qualifying attributes used to query this metric's telemetry. Keys are the metric store's own label names, not bare OTel attribute names: service identity arrives as "@resource.service.name" and "@resource.service.namespace", and the instrumentation scope as "@instrumentation.@name", while span-derived metrics label the service as a bare "service.name". Cloud provider, account and region are not repeated per metric — read those from the node. Values are RAW, deliberately NOT the node's normalized or merged identity, so a selector built from them matches the emitted series. A merged node can carry different values per metric, which is why these live here rather than on the node.
