tao.chenandClaude c4ac3cc354 Phase 5 Batch 2: 4 RM Tool + rm 客户端 + 日志降级链

- internal/rm/client.go: YARN RM 客户端
  - ListApps / GetApp / KillApp / GetLogs
  - GetLogs 降级链数据驱动 (amContainerLogs → aggregated-logs → logs)
  - 跨主机 redirect 保留 Authorization (URLAllowlist 兜底)
- 4 Tool: list_applications / get_application_status /
  get_application_logs / kill_application
  - mcp.WithEnum(state) 约束 YARN app 状态
  - tool handler 永远 (result, nil), 业务错误用 NewToolResultError
- deps.go: +HTTPClient + MaxResponseBytes
- main.go: 注入 httpclient.Client
- 端到端实测: mock RM 验证 4 Tool + 降级链 + 错误路径
