Github Sandbox File Downloader

This is a clever workaround for getting files into a GitHub repo without touching your local machine. You fork the repo, enable write permissions for Actions, then trigger downloads by committing messages like "download: https://example.com/file.zip" to main. A GitHub Actions workflow catches the commit, fetches the URLs, and dumps everything into a downloads folder. It's honestly pretty niche, but if you're working from a locked-down environment or want to script file ingestion into a repo without API tokens, it works. Just be aware of GitHub's storage limits and the fact that every download creates a new commit.
