feat(mcp-bridge): 实现MCP服务器功能增强和日志系统

- 添加日志缓冲区和封装日志函数，支持多种日志类型(info, success, warn, error, mcp)
- 实现MCP服务器启动/停止功能，支持端口配置和状态管理
- 添加配置文件管理(auto-start, last-port)，支持持久化设置
- 实现完整的工具API接口(get_selected_node, set_node_name, save_scene等)
- 统一处理MCP调用逻辑，便于日志记录和错误处理
- 更新面板界面，添加端口输入、自动启动开关、日志查看等功能
- 优化错误处理和响应格式，符合MCP标准规范
