refactor: 完善代码质量检查和修复系统

主要改进：
- 添加 make tox-local 本地代码质量检查支持
- 创建 check-code.sh 脚本支持独立工具执行
- 修复 51+ flake8 代码风格问题（未使用导入、行尾空格、注释格式等）
- 解决 pylint 变量命名和日志格式问题
- 重构 make_image 方法解决 too-many-statements 警告
- 添加类型注解和修复方法签名不匹配问题
- 统一代码风格规范（引号使用、空格格式等）

工具配置：
- 更新 tox.ini 支持 Python 3.10 本地环境
- 添加缺失的核心依赖包定义
- 完善 Makefile 构建系统集成
