Hyper-schema basic test plan

[handrews]

To get the hyper-schema work started, I plan to write a markdown file outlining the test cases. This will probably be done through multiple commits.

I think I still don't follow what it even means to test the hyper schema, but definitely looking forward to seeing what you have in mind!

@Julian the new examples section shows actual input and and output expectations.

See also the newly added output schema which is recommended rather than required, but it's what I'll build the test suite around.

Nice, will have a look, thanks.

Going to close this until hyper-schema is actively worked on again so there's something actionable to do here, but when that day comes, 100% agree we should add things for it.
