fix: mcp-auto-install cannot start (#9015)

* refactor(types): 将内置MCPServer类型从MCPServer分离并添加类型守卫

将内置MCPServer相关逻辑从通用MCPServer类型中分离，新增BuiltinMCPServer类型和类型守卫函数

* refactor(MCPService): 使用isBuiltinMCPServer检查内置服务器类型

修改传输层创建逻辑，通过isBuiltinMCPServer函数判断是否为内置服务器，并排除特定服务器

* refactor(types): 统一内置MCP服务器名称的键值格式并优化类型定义

将BuiltinMCPServers对象的键改为与值相同的格式，使结构更一致
同时简化BuiltinMCPServerName类型定义和isBuiltinMCPServerName检查逻辑

* refactor(types): 为内置MCP服务器名称添加类型定义

为`MCP_AUTO_INSTALL_SERVER_NAME`和`builtInMcpDescriptionKeyMap`添加`BuiltinMCPServerName`类型定义，提高类型安全性

* refactor(types): 重命名BuiltinMCPServers为BuiltinMCPServerNames以更准确描述用途

* style: 移除 TabContainer 组件中的多余空行

* refactor(mcpServers): 使用类型化的BuiltinMCPServerName替换字符串参数

将createInMemoryMCPServer函数的name参数从string类型改为BuiltinMCPServerName类型，提高类型安全性

* refactor(types): 重构内置MCPServer名称常量及类型定义

将BuiltinMCPServerNames的键名改为驼峰命名，并添加BuiltinMCPServerNamesArray常量
修改isBuiltinMCPServerName函数使用数组进行判断

* refactor(mcp): 使用枚举替换硬编码的服务器名称字符串
