Create a bounded GeoArrow aggregation for registration with
startColumnarWorkerHost.
The returned operation scans the input batch's packed buffers exactly once,
accumulates into group-indexed scalars, and emits a honua.aggregate result
batch. It fails closed — always before the output batch is allocated — when
the group ceiling is exceeded, when a metric value is non-finite, and when a
declared column does not exist in the batch. The input batch is never
mutated.
