feat: 上线前安全加固与发布工程化；appmall 由插件迁移为独立应用

安全（P0）
- 发布包签名：新增 scripts/package_keygen.php、scripts/package_verify.php、
  ywxapp\service\PackageVerifier；FrameworkService::apply() 解压前强制验签
  （ywxapp.framework_package_verify，默认开启）
- JWT 收紧：config/jwt.php 移除公开默认密钥，JwtService::assertStrongSecret()
  校验非空 / 长度≥32 / 已知弱值；.env.production.example 键名由 JWT_SECRET_KEY 修正为 JWT_SECRET
- /api/v1/Article：免登录白名单收窄为只读接口，写操作字段白名单 + assertOwner() 越权校验
- 开发者令牌：查找接口不再回显明文、统一失败文案 + 限流
- TemplateInstaller：文件名白名单 + realpath 归一化 + 目录内断言，修复 Zip Slip；补 use ZipArchive
- 后台登录：接入验证码、失败锁定与登录限流（config/ratelimit.php）
- 缓存 / Session 驱动可由 .env 覆盖（CACHE_DRIVER / SESSION_TYPE），集群部署改 redis
- paycenter 支付日志开关改为 PAY_LOG，不再跟随 APP_DEBUG

工程化 / 交付
- 新增 CHANGELOG.md 与 .env.production.example；composer.lock 入库锁定依赖版本
- 插件离线安装 CLI 增加 --uid，后台上传安装透传 uid，付费插件授权校验可通过
- 授权拒绝文案区分「未携带 uid」与「未找到有效授权」，便于排障
- .gitignore 放行 .env.production.example / .env.addon.example / .gitattributes / public/.htaccess

结构
- appmall 由 addon/appmall 迁移为独立应用 app/appmall（市场 / 开发者中心 / 审核 / 分润）
