The <name>_exception entries the fetcher uses to report per-groupBy, per-external-part,
derivation and codec failures. These are not part of the declared value schema, so they are
surfaced here rather than through the typed getters.

A named, nested view of a Chronon feature value.
Unlike the classic
Map[String, AnyRef]fetcher response, where struct-typed values are positionalArray[Any]and the field names live only in the schema, every level of a FeatureRecord is keyed by field name. Struct-typed fields resolve to nested FeatureRecords and lists of structs resolve toList[FeatureRecord], so callers can navigate arbitrarily deep nesting by name instead of by position.valuescarries everything the underlying fetcher response carried, including the<name>_exceptionkeys the fetcher uses to report partial failures (see errors).schemais narrowed to the declared fields actually present invalues.
