功能: 修复并实现多节点集群部署 (#38)
基础修复: - 新增节点离线检测:每 15s 扫描,超 45s 未心跳的远程节点自动置离线 - 节点删除前检查关联任务,避免孤立备份任务 - BackupTaskRepository 新增 CountByNodeID/ListByNodeID Master 端 Agent 协议: - 新增 AgentCommand 模型与命令队列仓储(pending/dispatched/succeeded/failed/timeout) - 新增 AgentService:任务下发、命令轮询、结果回收、超时扫描 - 新增专用 Agent HTTP API(X-Agent-Token 认证): /api/agent/heartbeat /api/agent/commands/poll /api/agent/commands/:id/result /api/agent/tasks/:id /api/agent/records/:id - BackupExecutionService 支持 node 路由:task.NodeID 指向远程节点时自动入队派发 Agent CLI(backupx agent 子命令): - 配置:YAML 文件 / 环境变量 / CLI 参数,优先级 CLI > 文件 > 环境 - 心跳循环 + 命令轮询循环 + 优雅退出 - 本地复用 BackupRunner 与 storage registry 执行备份并直接上传 - 支持 run_task 和 list_dir 两种命令 远程目录浏览: - NodeService 支持通过 Agent RPC 列出远程节点目录(15s 超时) 前端: - NodesPage 添加节点后展示 Agent 启动命令和环境变量配置 文档: - README 中英文重写"多节点集群"章节,含架构图、步骤、限制、CLI 参考
