Deploy to Railyard button

Let anyone deploy your open-source app to their own server with one click.

Add this to your README:

[![Deploy to Railyard](https://app.railyard.run/deploy/badge)](https://app.railyard.run/deploy?repo=https://github.com/OWNER/REPO)

Clicking it signs the visitor in (or up), then opens New app with your repository already read — framework, processes, databases and documented variables filled in. Add &branch=NAME to deploy a specific branch.

For apps in the template catalog, link to https://app.railyard.run/deploy?template=KEY instead.
