fix(frontend): 汉化MCP工具展示并折叠原始说明

 - Plugin/Skill/Provider 无记录时显示空状态，模型发现失败时允许使用真实的手动模型 ID。
 
 验证：前端 81 项测试、类型检查与生产构建通过；后端 454 项测试通过。新增测试覆盖空初始状态、离线错误、真实统计与权限、测试 Provider 过滤、真实聊天历史及旧流隔离。本次未调用真实付费推理 API。
+
+### MCP 工具中文展示补充
+
+Agent 工具列表按 `mcp.<server_id>.<remote_name>` 的远程工具名匹配中文展示，支持 `web_search`（网页搜索）、`understand_image`（图像理解），并补充 `text.uppercase`（文本转大写）。此映射只影响界面，工具调用与权限选择仍使用完整原始 ID。
+
+卡片默认显示三行摘要，完整服务原文可展开查看，展开操作不会改变工具选择。服务已提供中文说明时优先保留；未收录的 MCP 工具明确提示暂无中文说明，不将本地摘要当作服务协议或自动翻译结果。原始说明及其中的参数规则完整保留。
+
+验证：前端 84 项测试、类型检查与生产构建通过。新增回归覆盖不同服务器命名空间、未知工具、服务中文说明、原文完整性，以及选择工具时保留原始 ID。
