 * Every unique key on a table, as DB column-name tuples. Primary keys count —
 * fan-out detection asks "do these join columns cover a unique key?", and a PK
 * answers that as well as any explicit unique constraint.
 *
 * Returns `undefined` if reflection fails (non-pg table, or a drizzle version
 * without config access), meaning "unknown, cannot determine". Returns `[]`
 * when reflection succeeds and the table genuinely has none. That distinction
 * is load-bearing: `hasRichMeta` uses it to tell "metadata unavailable" from
 * "confirmed no constraints", and projection validation fails closed on the
