   * - The size of this C++ object (`sizeof(*this)`),
   * - All rows and columns (including column name strings),
   * - String values stored in the result set,
   * - ArrayBuffers used for BLOB columns (object overhead + raw byte size),
   * - Column metadata strings.
   *
   * This is a best-effort estimate and intentionally focuses on external
   * heap allocations that can put pressure on the JS GC.
