feat: 重构为多类型 checker 通用框架，支持 HTTP 与命令检查
- 引入 typed target 判别联合，支持 http 与 command 两种 checker - expect 重构为有序规则数组，按配置顺序快速失败并生成结构化 failure - 新增 command runner，支持 exec + args 本地命令执行 - 引入全局并发限制 maxConcurrentChecks 和 size 解析 (KB/MB/GB) - HTTP/command 各自独立 expect pipeline，应用领域默认成功语义 - SQLite schema、API、Dashboard 全链路调整为 checker 通用契约 - 补充完整测试覆盖（192 tests），更新 README 与示例配置
