/**
 * @fileoverview `brapi_find_variants` — find variant records by variant set,
 * reference, or genomic region. Standard find_* pattern — distributions +
 * dataframe spillover. Note: the BrAPI filter catalog uses `start` / `end` as
 * single scalars (1-based inclusive / exclusive) per the spec.
