chore: 升级到 Python 3.14 并现代化代码

- 升级 Docker 基础镜像从 Python 3.12 到 3.14
- 更新 pyproject.toml 支持 Python 3.13/3.14
- 移除 Python 3.8/3.9/3.10/3.11 分类器
- 更新 black 和 mypy 配置目标版本
- 将 get_event_loop() 替换为 get_running_loop() 加上 RuntimeError 处理
- 简化 compute_cost_sync 中的 asyncio.run 使用
- Dict/List/Tuple/Set → dict/list/tuple/set (PEP 585)
- Optional[T] → T | None (PEP 604)
- Union[A, B] → A | B (PEP 604)
- 移除废弃的 typing 导入
- 移除不必要的字符串引号注解
