Updated download management repo (hillmanation\Mangadex-Batch-Downloader) to then read this staging list at nightly batch download task add urls to the manga_list.txt download list that don't already exist, and git commit them to the repo to keep the download jobs up to date
That repo then deletes the staging file from the defined location to reset the lookup task at the next run, if a user has requested a new manga be added
