chore: baseline — ORM migration + systemd deploy + MCP server + daily check

- ORM migration: models/ops 重构
- deploy: 标准化 systemd timer/service 部署体系
- MCP server: 5 个只读工具(任务/状态/数据集)
- daily check: 数据一致性巡检
- watch: task_watch 后台监控
- kline_daily: 麦蕊优先,时间门禁15:00
- 删除: task_industry_sector, task_sector_features
