fix(task) #232 Fix edge cases looping forever or failing with a `TypeError`: validate FileSplitterTask `max_lines` (greater than 0, also when given as input), catch any `\Throwable` in PropertySetterTask, type SlugifyTransformer options, explicit exceptions in InputFolderBrowserTask (no folder path) and `XmlFile::write()` (`saveXML()` failure). Update documentation, add tests. · cleverage/process-bundle@7744655
