研究方向
Examine the existing CLI options implementation in npm run all, likely in the main entry file or a CLI module. Look for how other options like parallel and sequential are parsed. The request is for a waterfall flag; determine if it means sequential execution with a specific behavior. Check the issue comments for any clarification or maintainer input. Since there are no linked PRs, consider proposing an implementation that adds a simple flag to run tasks sequentially.
