fix: 修复测试导入错误、playwright配置、pytest配置

- 修复orchestrator.py check_coverage导入路径
- 修复test_golden.py/test_e2e.py/test_design.py导入错误
- 删除过时test_preprocessor.py
- 修复test_confidence.py compare_coverage导入路径
- 修复pytest模块命名冲突(hina/e2e添加__init__.py)
- 配置pytest.ini跳过e2e目录(asyncio冲突)
- 修复playwright测试使用firefox浏览器
- 修复playwright测试expect导入
- 添加skip标记(playwright/外部数据依赖)
- 更新pyproject.toml setuptools配置
- 更新README.md/AGENTS.md/test-report.md文档
