AI Features like Intellience, MCP disappear after rebuild with plugins

使用列出的 ./answer 构建命令复现该问题，并比较重新构建 v2.0.0 Linux amd64 二进制文件前后的管理页面和 HOST/admin/mcp。跟踪 Intelligence 功能在启动期间的注册或加载方式；完成标准是插件重新构建后，它仍显示在管理页面中，并且可以通过 MCP 端点调用。

Describe the bug

When I rebuild binary with plugins with this command:

./answer build --with github.com/apache/answer-plugins/connector-basic --with github.com/apache/answer-plugins/reviewer-baidu --with github.com/apache/answer-plugins/reviewer-basic --with github.com/apache/answer-plugins/storage-s3 --with github.com/apache/answer-plugins/storage-aliyunoss --with github.com/apache/answer-plugins/storage-tencentyuncos --with github.com/apache/answer-plugins/search-algolia --with github.com/apache/answer-plugins/quick-links --with github.com/apache/answer-plugins/render-markdown-codehighlight --with github.com/apache/answer-plugins/captcha-basic --with github.com/apache/answer-plugins/captcha-google-v2 --with github.com/apache/answer-plugins/connector-dingtalk --with github.com/apache/answer-plugins/notification-dingtalk --with github.com/mike-brown8/answer-connector-furtv/connector-vds
