This commit introduces a new `/core:sync` command that syncs changes across dependent modules.
The command reads a `repos.yaml` file to determine the dependency graph. When a base module is changed, the command will:
- Update the `composer.json` file of each dependent module to the latest version of the base module.
- Run `composer update` to install the new dependency version.
- Run tests in each dependent module to ensure that the changes have not introduced any regressions.
The command also includes a `--dry-run` option that allows users to see what changes would be made without actually modifying any files.
