pymsg 客户端: - MsgClient.call() 新增 retry_on_refused/retry_interval 参数 - retry_on_refused=True 时，ConnectionRefusedError 不抛出，按 retry_interval(默认1s)阻塞重试 - 重试期间每5秒向 stderr 打印等待提示，避免日志刷屏 - 仅对 ConnectionRefusedError 重试；TimeoutError/ConnectionError/RpcError 仍立即抛出 - 默认 retry_on_refused=False，完全向后兼容 - RpcClient 构造函数新增同名关键字参数，call() 支持单次调用覆盖 - 新增 time 模块导入 - 更新 README 文档（新增"启动等待模式"章节和参数表） 各服务（db/dnfs/static）: - _fetch_from_confs() 改用 retry_on_refused=True，移除手动 ConnectionRefusedError 捕获和 sys.exit - 保留 RpcError（如配置文件不存在）的友好错误处理和 sys.exit(1) - 启动时不再因 confs 未就绪而退出：pymsg 自动阻塞等待 confs 启动后自动连接成功 - 启动顺序从"刚性要求 confs 先启动"变为"不严格要求启动顺序" - log_client 保持默认 retry_on_refused=False，后台线程不阻塞（fail-safe 丢弃日志） - 更新各服务 README 和 confs README 的启动顺序描述 测试验证: - 基本 call() 正常工作 - retry_on_refused=False 连接拒绝立即抛 ConnectionRefusedError - retry_on_refused=True 阻塞等待（延迟1.5s启动服务后成功连接，重试日志正常输出）
