用法：
  ./app.sh <命令> [参数]

常用命令：
  help                     显示帮助
  install                  安装开发依赖：uv sync --extra dev
  test                     运行测试：uv run pytest -q
  serve [端口]             本地启动，默认 8000
  migrate                  执行 Alembic upgrade head
  migration <说明>         生成 migration，说明建议以作者名开头
  heads                    查看 Alembic heads
  current                  查看当前 Alembic 版本
{% if include_system %}  system-sync              同步 iti-system migration 到当前项目
  system-seed              初始化 / 更新系统 seed
  init-system              system-sync + migrate + system-seed
{% endif %}  init                     install + migrate{% if include_system %} + system-seed{% endif %}

示例：
  ./app.sh install
  ./app.sh serve 8000
  ./app.sh migration "alice add order table"
{% if include_system %}  ./app.sh init-system
{% endif %}
