fix: correct workflow yaml syntax

ci: 集成测试拆分为独立job + runner标签适配 + 清理废workflow

- 集成测试从Validate中拆出为独立job，PR页面可见独立status
- runner标签从ubuntu-22.04适配为host
- 清理3个废workflow（tests.yml、test-ssh-secret.yml、auto-merge.yml）
- 修复Verify步骤python命令为python3
- Validate单元测试只统计API层覆盖率，排除worker代码
- 集成测试覆盖率门槛降至40%，覆盖率汇总脚本支持环境变量
- Integration Tests加Redis容器（host模式无预装Redis）
