AckdbObserveEventFieldCondition

A condition on a promoted event-metadata field's reduced scalar value (#212). `columnKey` is the synthetic field-catalog key (`emf__<source>__<field>` for the latest value, or `…__sum` for a numeric running total) and is whitelisted against the catalog; the operator must be legal for the field's valueType (same legality as a trait of that type).
