refactor: 简化 optimizeDeps 样式清单生成，工具函数移至文件底部
- 内联一次性小方法：toElementPlusName / collectSideEffects 不再单独定义 - 指令与组件共用组件 resolver：v-loading 等经 ElLoading 解析，已实证与 指令 resolver 的 sideEffects 完全一致，删除指令 resolver 与第二循环 - 工具函数统一放到 defineConfig 之后，文件顶部只保留 imports、常量与主配置 - 行为零变化：生成清单仍为 68 项，与重构前逐字节一致（loadConfigFromFile 回归验证）
