在 Agent 资源检索投影中暴露分类与自定义标签

- agent/direct_tool_bridge.rs：bridge_registered_resource 投影新增 category 与 tags，位置固定在 mediaType 之后，保持稳定字段顺序
- agent/direct_tool_bridge.rs：category 直接取 manifest 条目已解析的功能分类（显式合法值原样保留，历史缺字段时已按 kind 派生），tags 缺失时为空数组，不改变 manifest 结构与对外契约
- agent/direct_tools_mcp.rs：agc_list_registered_assets 工具描述补上功能分类与自定义标签，与新增输出字段保持一致
- agent/direct_tool_bridge.rs：既有序列帧投影测试补充 category 与 tags 默认值断言
- agent/direct_tool_bridge.rs：新增 bridge_registered_resource_projects_manifest_classification_verbatim，锁定显式分类与标签原样透出且不泄漏 prompt / model
