/**
 * @fileoverview `brapi_germplasm_performance` — aggregate a single germplasm's
 * observations across the studies it appears in, returning per-variable summary
 * statistics (n, mean, median, sd, min, max) plus the contributing studies and
 * seasons. Answers the breeder's primary question — "how does line X perform
 * across the pool's history?" — in one call.
 *
 * Study-anchored by design: a naked `/observations?germplasmDbId=…` pull stalls
 * on SGN/Breedbase deployments (the count-probe bailout). Instead the tool
 * discovers the germplasm's studies via `/studies?germplasmDbIds=…` (with a
 * dialect-honor cross-check, since some servers silently drop that filter and
 * return the global list), then pulls observations per study through the shared
 * `pullStudyObservations` machinery — the same `/observations` →
 * `/observationunits` fallback chain `brapi_build_phenotype_matrix` uses.
 *
 * Returned rows are filtered to the iterated study and the target germplasm, so
 * the aggregate stays correct even on servers that ignore the studyDbId filter
 * on `/observations` (the BrAPI Community Test Server does) or over-return from
 * the germplasm-anchored fallback.
 *
