feat: Q4 测试覆盖 + 插件生态 — 集成测试/E2E/进销存插件/热更新

Q4 成熟度路线图全部完成:

1. 集成测试框架 (Testcontainers + PostgreSQL):
   - auth_tests: 用户 CRUD、租户隔离、用户名唯一性
   - plugin_tests: 动态表创建查询、租户数据隔离

2. Playwright E2E 测试:
   - 登录页面渲染和表单验证测试
   - 用户管理、插件管理、多租户隔离占位测试

3. 进销存插件 (erp-plugin-inventory):
   - 6 实体: 产品/仓库/库存/供应商/采购单/销售单
   - 12 权限、6 页面、完整 manifest
   - WASM 编译验证通过

4. 插件热更新:
   - POST /api/v1/admin/plugins/{id}/upgrade
   - manifest 对比 + 增量 DDL + WASM 热加载
   - 失败保持旧版本继续运行

5. 文档更新: CLAUDE.md + wiki/index.md 同步 Q2-Q4 进度
