Lime 质量任务规划器

用法:
  node scripts/quality-task-selector.mjs
  node scripts/quality-task-selector.mjs --staged
  node scripts/quality-task-selector.mjs --base origin/main
  node scripts/quality-task-selector.mjs --format github

选项:
  --full          忽略改动检测，返回全量任务
  --staged        仅基于已暂存文件判断
  --base REF      基于指定基线判断
  --format FMT    输出格式：json | github
  -h, --help      显示帮助
