/**
 * This script runs the following tasks:
 * 
 * 1. Tag main packages defined in `.changeset/config.json` if they are not tagged with the current version in `package.json`;
 * 2. If no new git tag added, exit;
 * 3. If at least one new git tag found, run `pnpm -r publish` and `git push --tags`.
 * 
 * The subsequential release tasks, such as create GitHub release and build Docker image, will be took over by GitHub workflows.
