I went through https://github.com/astral-sh/ty/issues/1274 and tried to
extract what I could into eval tasks. Some of the suggestions from that
issue have already been done, but most haven't.
This captures the status quo.
This is still early days, but I hope the framework introduced here makes
it very easy to add new truth data. Truth data should be seen as a form
of regression test for non-ideal ranking of completion suggestions.
I think it would help to read `crates/ty_completion_eval/README.md`
first to get an idea of what you're reviewing.
