/**
 * A marker trait for types that support cloning without having to copy all indexed values.
 *
 * This likely means that either:
 *
 * - The type uses persistent data structures internally (e.g., `crate::index::im::BTreeIndex`)
 * - The type only works using aggregations that do not store all samples (e.g., `crate::aggregation::Count`)
