fix(v0.3.0): 框架内 peer 引用回退静态 import + 修 FieldRelativeTime 路径

- 覆盖颗粒度只在 3 个入口: router targets / module routes / field registry
- 框架内 .vue 之间互相引用全部硬编码静态 import,resolveVue/defineAsyncComponent 退出 .vue 文件
- 修 components/fields/FieldRelativeTime.vue 的 ../VueAdmin → ../../VueAdmin (移动后未跟改)

src/components/userbar.vue
