ETS owner for the named ETS table — aggregated
datapoints keyed by {stream_name, attrs} (spec
metrics/data-model.md §Metric). InstrumentationScope
is hardcoded SDK-wide so it is omitted from the key.
Same SpanStorage-style GenServer-as-owner pattern as the
other Metrics storage modules — table is public with
concurrency flags so the recording / collection paths bypass
the GenServer.
