/**
 * SC-P-10 创建任务+下发（task.parent.createTask / S-cfc-12）— API 级 e2e
 * ================================================================
 * 场景（tests/user-scenarios/应用场景总览.md 业务域B / 02-parent.md P-4）：
 *   建任务（成员/积分/频率）→ 下发 → B 列表待执行；边界：重复提交不重复发分、频率/截止边界。
 * 关联用例：test-cases/parent.md TC-P-05（正常）/ TC-P-05-E（异常）/ TC-P-05-P（权限）。
 * 设计锚点（API_REFERENCE.md 4.3 / family-management-flow.md）：
 *   POST /api/tasks/create（TaskController→TaskService.createTask）、POST /api/tasks/today。
 *
 * 运行：
 *   本 feature 分支实现（本地/自建实例）：npx playwright test api/task-create-scp10.spec.js \
 *     -c playwright.config.api.local.js --project=desktop
 *   远端已部署基线：npx playwright test api/task-create-scp10.spec.js \
 *     -c playwright.config.api.js --project=desktop
 *   （异常流/越权注入类用例仅在本 feature 实现上通过——远端基线无参数校验/幂等/跨家庭校验）
