"""补齐运营（`operator`）角色的权限，并按需创建该角色。

## 为什么需要它

`operator` 是场外/推广线建的角色，**不在 `seed_test_rbac.py` 的 9001-9003 里** ——
所以种子既不会创建它，也不会清理它的绑定。库里这个角色长期**只有 1 项权限**
（`offsite:write`），但两条线实际要求的并不一样：

| 功能 | 门槛类型 | 位置 |
|---|---|---|
| 场外基金运营（邮件、单据、确认、通知、结算） | **角色门槛** `{"operator","risk_operator","admin","super_admin"}` | `offsite_fund_service.py:2600` |
| 金融 NL2SQL | **权限码** `financial:nl2sql:read`（角色白名单含 `operator`） | `financial_nl2sql_service.py:272` |

也就是说：场外主体功能**本来就该能用**（靠角色），运营真正缺的是 NL2SQL 那一个码；
而"看不到运营界面"是前端没做，不是权限问题。

## 给哪些 —— 按代码真实要求，不多给

运营不做治理、不看审计、不发布配置，因此**不给** `audit:read` / `config:*` /
`product-governance:*` / `knowledge:manage`。需要排查权限缺口时跑
`python tools/check_permission_coverage.py`。

本脚本**只增不删**，可重复执行。

用法：

    python tools/grant_operator_role.py --dry-run
    python tools/grant_operator_role.py
