feat: 工具系统迁移 + 重型插件骨架 + 前端交互增强

- 工具系统从 kilostar/plugin/tool_plugin/ 迁移到 data/toolset/（manifest.json 声明式）
- 新增 plugin_runtime 模块：BaseOrganization / GlobalPluginManager / loader / tool_bridge
- 新增 org_task + org_task_event 表及 DAO（alembic 0009）
- 新增 /api/v1/plugin 路由（submit/status/stream/install/reload）
- 新增 data/plugin/example_dept 示例重型插件
- regulatory_node 支持聊天历史上下文注入
- send_file 改为 artifact 存盘 + SSE 推送下载链接
- 前端 WorkflowFileCard 组件 + ToolSettings README 渲染
- utils 整理：合并 access/role_check、standalone_proxy→ray_compat、删除废弃模块
- 项目结构文档移至 docs/STRUCTURE.md 并详细展开
