"""工具调用 API(api-spec §15)。
- GET /tools:列出已注册工具策略元数据(从 tool_policies 表,含 executable 派生)。
- POST /tools:注册自定义工具策略(百工枢器用治理声明,记审计)。
- GET /tools/calls/{tool_call_id}:单次工具调用事件详情。
- PATCH /tools/{tool_name}:编辑工具策略元数据(spec §15: risk_level 等)。
- DELETE /tools/{tool_name}:注销自定义工具(builtin 不可删)。
- POST /tools/{tool_name}/invoke:调用工具;高风险返回 requires_confirmation + confirmation_id,
交由 /safety/confirmations/{id}/approve 消费。
- POST /tools/{tool_name}/invoke/stream:流式调用(SSE),实时推送 tool.stdout/tool.stderr
增量与 tool.completed;司命 deny/ask-未确认/沙箱错误分别以 tool.failed / tool.requires_confirmation 结束流。
策略写操作(POST/PATCH/DELETE)后刷新 ToolRuntime 的司命决策器,使变更即时生效;
tool_runtime 未就绪时仅写库(重启后从 db 加载)。
