iTi-Flask 开发脚本

用法：
  ./scripts/iti.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
  check                        运行测试和 mypy
  serve [端口]                 启动框架示例应用，默认 8000
  migrate                      执行当前仓库 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
  make-app <目录> [包名]        从当前框架仓库模板生成业务项目
  make-system-app <目录> [包名] 生成带 iti-system 的业务项目
  release [版本]               发布框架：测试、改版本、提交、打 tag、推送

示例：
  ./scripts/iti.sh install
  ./scripts/iti.sh test
  ./scripts/iti.sh serve 8000
  ./scripts/iti.sh make-app ../hsyh-erp hsyh_erp
  ./scripts/iti.sh make-system-app ../hsyh-mes-phase2 hsyh_mes_phase2

说明：
  - 默认生成项目使用 copier-template 里的 Git 依赖配置。
  - 临时本地验证可在生成时按 copier 交互改成 file://。
