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。

   - The Capabilities section is critical - each capability listed will need a spec file.
 - **specs/<capability>/spec.md**: Create one spec per capability listed in the proposal's Capabilities section (use the capability name, not the change name).
 - **design.md**: Document technical decisions, architecture, and implementation approach.
-- **tasks.md**: Break down implementation into checkboxed tasks, following TDD workflow structure:

-  **TDD Tasks Structure (MUST follow)**:
-  ```markdown
-  ## 0. 测试准备（实现前执行）
-  - [ ] 0.1 生成验收测试和流程测试（/opsx:gen-tests）
-  - [ ] 0.2 运行测试确认全部 FAIL（证明测试有效）
-
-  ## 1. 基础设施（数据库 + Model）
-  - [ ] 1.x 创建迁移、Model、DTO
-  - [ ] 1.y 验证：编译通过
-
-  ## 2. 功能单元 A（完整垂直切片）
-  - [ ] 2.1 Store 层
-  - [ ] 2.2 Service 层
-  - [ ] 2.3 Handler 层 + 路由
-  - [ ] 2.4 **验证：功能 A 相关验收测试 PASS**
-
-  ## N. 最终验证
-  - [ ] N.1 全部验收测试 PASS
-  - [ ] N.2 全部流程测试 PASS
-  - [ ] N.3 完整测试套件无回归
-  ```
-
-  **Key principles**:
-  - Task group 0 MUST be test preparation (generate tests + confirm all FAIL)
-  - Organize by functional units, NOT by technical layers (Store/Service/Handler)
-  - Each functional unit MUST end with "verify related tests PASS"
-  - Final validation MUST include all acceptance + flow tests passing
