==> 完成。启动方式:

  # 后端(默认 USE_FAKE_DATA=true,无需 DB 即可起)
  cd apps/api && .venv/bin/uvicorn app.main:app --host 0.0.0.0 --port 8000

  # 前端(--host 暴露到局域网/远程访问)
  corepack pnpm@10 --filter @hs-data/web dev --host

  # 接真实 Postgres(可选):
  docker compose -f infra/docker-compose.yml up -d
  cd apps/api && .venv/bin/alembic upgrade head && .venv/bin/python -m scripts.seed
  # 然后把 apps/api/.env 的 USE_FAKE_DATA 设为 false 再起后端

  # 测试
  corepack pnpm@10 --filter @hs-data/web test
  cd apps/api && .venv/bin/pytest -q
