21D — 后端: - Claims 新增 LicenseExpiresAt (*int64 unix 秒)，写入 JWT 避免每次查库 - middleware/license_guard.go: CalcLicensePhase / LicenseGuard / GetLicensePhase - grace(0-7d): 允许通行 - readonly(7-15d): 拦截非 GET 写操作 → 403 - locked(15d+): 全部拦截 → 403 - auth.go: issueTokens 在 JWT 中嵌入 license expires_at；Login 检查 locked 拒绝登录 - router: license/* 路由豁免 LicenseGuard（锁定时仍可激活/查状态） 21E — Flutter 前端: - models/license.dart: 新 LicenseInfo，含 phase/maxDevices，去掉旧 activatedAt - core/device/device_id.dart: 持久化 UUID-v4 作为设备 ID（SharedPreferences） - repositories/license_repository.dart: getInfo/activate/deactivate，激活时携带设备信息 - providers/license_provider.dart: 改接 LicenseRepository - settings_screen.dart: activatedAt 改为显示 maxDevices Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
