-背景：
-小程序端 getOrCreateDefaultProject 在重试/并发/前端重复调用下，
-仅靠应用层"先查再插"不保证幂等，会给同一用户重复创建默认项目。
-
-改动：
-1. projects 表新增 is_default 布尔列（默认 false）
-2. 部分唯一索引 uq_projects_owner_default：(owner_user_id) WHERE is_default = true
-   —— 保证每个用户至多一个默认项目
-3. 存量数据回填：把名为"默认项目"的存量项目按创建时间最早者标记为 is_default=true

-"""MediaKit 客户端 — 封装火山引擎 AI MediaKit 对口型 API.
-
-接口文档：https://docs.volcengine.com/docs/6448/2656064
-
-异步任务流程：
-1. POST /api/v1/tools/lip-sync  提交对口型任务 → 返回 task_id
-2. GET  /api/v1/tasks/{task_id} 轮询任务状态 → running/completed/failed
-3. completed 时 result.video_url 为口型对齐视频（临时链接 24h 有效）
-
-设计原则：
-- API Key 从配置读取（settings.mediakit_api_key）
-- 未配置 API Key 时所有方法返回降级响应，不阻塞主流程
-- HTTP 超时/网络异常统一包装为 MediaKitError
