 - 遍历 workflow 数组，为每个动作创建步骤节点
 - 参数重命名: asp_vol -> asp_vols, dis_vol -> dis_vols, asp_flow_rate -> asp_flow_rates, dis_flow_rate -> dis_flow_rates
+- 参数输入转换: liquid_height（按 wells 扩展）；mix_stage/mix_times/mix_vol/mix_rate/mix_liquid_height 保持标量
 - 参数扩展: 根据 targets 的 wells 数量，将单值扩展为数组
     例: asp_vol=100.0, targets 有 3 个 wells -> asp_vols=[100.0, 100.0, 100.0]
 - 连接处理: 如果 sources/targets 已通过 set_liquid_from_plate 连接，参数值改为 []
