' ==============================================================================
' 模块: M08_ComponentProcessor
' 职责: 处理"部件"物料的特殊逻辑
'
' 部件物料特性:
'   - 每条"部件"记录包含三个物料的数据：
'     1. 部件物料本身
'     2. 接头物料（子件1）
'     3. 弹性元件物料（子件2）
'
' 选择策略:
'   - 优先选择"部件"物料
'   - 当"部件"物料库存不足时，选择"接头"+"弹性元件"
'   - 库存检查接口预留，当前默认返回True（库存充足）
'
' 验证规则:
'   - 正常组合1: 1个部件
'   - 正常组合2: 1个接头 + 1个弹性元件
'   - 异常: 其他组合（如只有接头、只有弹性元件、同时有部件和接头等）
