feat: 更新为 1.2.0 构建产物（内核重构版）

- 产物替换为 funjiaui.es.js / funjiaui.cjs.js / funjiaui.umd.js
- style.css 更新，新增 index.d.ts 与各组件类型声明目录
- 移除旧产物 um_table.es.js（1.0.0 的 ES 包，历史与 v1.0.0 标签仍可回溯）
- package.json 补齐 module / types / unpkg / jsdelivr / files 字段，
  并将 vue、element-plus、@element-plus/icons-vue 声明为 peerDependencies
- 新增 README 说明产物清单与用法
