fix: 解决 mypy 模块重复识别问题并优化项目配置

**根本问题**：
- 项目中同时存在 `src.dynamic_params` 和 `dynamic_params` 两种导入方式
- mypy 同时检查了 Pip 已安装的包和源码，导致模块重复识别错误

**解决方案**：
1. **统一导入方式**：
   - 修改测试文件中的导入语句，从 `from src.dynamic_params` 改为 `from dynamic_params`
   - 确保所有代码使用一致的导入路径

2. **优化 mypy 配置**：
   - 将 mypy 配置到 `pyproject.toml`里
   - 设置 `mypy_path = "src"` 确保 mypy 正确查找模块
   - 配置 `exclude` 规则，避免重复检查

3. **修复类型注解问题**：
   - 移除函数外部的类型注解（mypy 不支持在函数外部声明类型注解）
   - 为动态添加的属性添加 `# type: ignore[attr-defined]` 注释

4. **代码风格优化**：
   - 修复 flake8 行长度错误，将超过 88 个字符的行分成多行
  - 配置 pyproject.toml 中的 flake8 设置，添加对 ANN 类型注解错误的忽略
 - 修复 pre-commit 配置文件，移除 flake8 的 --config 参数：否则，flake8 会尝试解析 pyproject.toml 文件，报错信息显示在多个行上有 ']\n' 这样的解析错误
   - 修复 black 配置中的未转义反斜杠问题
