"""FastAPI 入口。挂载路由,放行前端跨域,启动时同步接口定义。

启动:  uv run --with-requirements requirements.txt uvicorn app:app --reload --port 8000

路由分组(对齐 dograh 的 routes/ 结构):
  /health              健康检查
  /api/assistants      助手 CRUD
  /api/interface-definitions 接口定义
  /api/model-resources 模型资源 CRUD
  /ws/voice            WebRTC 输出(浏览器)
  /ws/stream           WS 输出(裸音频流)
  /api/webrtc/ice-servers  WebRTC STUN/TURN 配置
