// 这些测试约束「scope 命名统一」契约：
//   - 只有 nezha:* 一套是 first-class scope；
//   - mcp:* 不再作为 HasScope 的别名（避免 mcp:fs:write 静默扩到 REST 的 nezha:server:write）；
//   - AllScopes / AdminOnlyScopes 不再包含 mcp:*，新建 token 不能再签发它们。
//
// 旧 mcp:* 兼容由 createAPIToken 入口做一次性归一化（mcp:fs:read 等只读/exec 映射到
// 对应的 nezha:* read/exec），但 write/delete 类不再映射；详见 controller.createAPIToken。
