"""发布风控 Agent 的运行期配置：意图配置 + 意图工具白名单。

配置来源：组员交付的 `20-Agent工具白名单与意图配置.md` 与两份 JSON。
工具名与权限已核对与代码一致（`risk_agent.py:24-26` 定义常量、`bootstrap.py:206-225` 注册，
`required_permission` 均为 `risk:alert:read`）。

两个必须讲清的点（与 `publish_customer_service_config.py` 同源）：

1. **为什么必须发这一步**：工具白名单是**失败关闭**的——`ToolExecutor` 拿发布配置里
   `agent_tools` / `risk:<intent>` 的 `allowed_tools` 与代码声明的
   `AgentDefinition.allowed_tools` 取交集，缺配置时交集为空、任何工具调用都被拒。
   「Agent 写好了但没发配置」的表现是"风控什么都答不了"。

2. **为什么必须继承现有配置项**：`config_release` 是**整版本替换**语义——激活新版本后，
   旧版本的所有配置项都不再生效。若只发布风控自己的白名单，客服的 4 条白名单与示例 Agent
   的 `fund_query_demo:fund_quote` 会被静默清空（客服表现为"一直转人工"）。所以发布前先把
   当前 effective 版本里的配置项原样搬进新版本，再追加本次新增项。
