移除所有测试代码和测试要求

**变更说明**:
- 删除所有 *_test.go 文件（单元测试、集成测试、验收测试、流程测试）
- 删除整个 tests/ 目录
- 更新 CLAUDE.md：用"测试禁令"章节替换所有测试要求
- 删除测试生成 Skill (openspec-generate-acceptance-tests)
- 删除测试生成命令 (opsx:gen-tests)
- 更新 tasks.md：删除所有测试相关任务

**新规范**:
- ❌ 禁止编写任何形式的自动化测试
- ❌ 禁止创建 *_test.go 文件
- ❌ 禁止在任务中包含测试相关工作
- ✅ 仅当用户明确要求时才编写测试

**原因**:
业务系统的正确性通过人工验证和生产环境监控保证，测试代码维护成本高于价值。
