Build the bleve and OpenSearch index mappings from the Go struct via reflection (json tags + per-field overrides) instead of hand-rolled mappings and hit deserializers. New mapping package: BleveBuildMapping, OpenSearchBuildMapping, Deserialize[T], PrepareForIndex; field decoding is fail-soft. Mtime is typed as a date so mtime ranges are chronological on both backends. Route CS3 facet parsing through mapping.DeserializeStringMap. The any-valued (bleve hit) and string-valued (CS3 metadata) deserializers share one generic fillStruct walker with a per-value setLeaf callback.
