Along with the videos (see #68), it would be good to have a demo repository that people can use to get to know contextive interactively.

When looking at the other repos in the dev-cycles org, there are two that showcase how to use contextive across multiple repos. That's an advanced use case and the definitions.yml is a bit short. Not a good demo for newcomers, I think.

In @chrissimon-au 's personal repos, there are tdd-ddd-demo-dotnet and tdd-ddd-demo-java, which also serve as a good demo for contextive. But they take some digging to find.

It would be good to have a link in the readme of this repo to a demo repo in the dev-cycles org that people can use to try out contextive. Preferably with a .devcontainer and a codespaces link where everything is already set up. It could get pretty fancy with a code tour (another nice documentation tool).
