将工具管理从"agent 挂单个 tool"改为"agent 挂 toolset"模式： - 三个系统预置工具集（system_basic/system_chat/system_workflow）入 DB - 新增 send_file 工具（系统对话工具集）、修复 approval actor 调用 bug - 后端 agent 加载全部走 toolset 链路，移除 load_tools_from_list - 前端工具集中心卡片展示 + agent 配置改为 toolset 多选 - resource API 增加 category 过滤与系统 toolset 保护 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
