fix: 降低 Python 版本要求至 3.10

问题：
- 项目要求 Python 3.14（未发布版本），用户无法正常安装
- 代码实际只使用了 Python 3.10 的特性（X | None 类型注解）

修改：
- pyproject.toml: requires-python、ruff/mypy target 改为 3.10
- CI 配置: python-version 改为 "3.10"
- README/README_CN: 文档中的版本要求改为 3.10+

额外修复：
- interactor.py: 修复 Python 2 风格的异常捕获语法（需括号）
- base.py/win_job.py: 添加 __future__ annotations 支持自引用类型
