The live UI is updated from the info in `LiveStageMetrics`, which is not
written to the store. That's kept in memory while executions are running, and
aggregated into the final metrics view when the execution finishes (see
`aggregateMetrics`).
`SQLAppStatusStore.executionMetrics` has logic to call the listener
directly when the final metrics are not yet computed.
