bugfix

[TyperBody]

1. 添加依赖验证步骤

   async def verify_dependencies(deps: list[str]) -> list[str]:
       """验证依赖是否真正安装成功"""
       missing = []
       for dep in deps:
           pkg_name = dep.split('==')[0].split('>=')[0].split('<=')[0]
           if importlib.util.find_spec(pkg_name) is None:
               missing.append(dep)
       return missing

2. 添加重试机制

   async def install_with_retry(dep: str, max_retries: int = 3):
       for attempt in range(max_retries):
           returncode, _ = await install_single_async(dep)
           if returncode == 0:
               return True
           await asyncio.sleep(1)  # 等待后重试
       return False

3. 改进错误反馈

   • 前端显示详细的依赖安装状态
   • 提供"重新安装依赖"按钮
   • 失败时显示具体的 pip 错误输出

4. 依赖预检查

   • 安装前检查依赖冲突
