Does jq allow for comments in JSON? Can we annotate what these things mean?

Actually, can we skip jq and just parse it out in JS instead? And can we also have that as a ts file that we run via like tsx prepare-matrix.ts?

[meeroslav]

The jq does not support jsonc format.
We can load and parse it within script, yes.

We can wrap entire logic within prepare-matrix.ts and execute it to retrieve matrix JSON. I wanted to avoid ts files to make things "closer to the metal" but I guess there is benefit on wrapping the entire logic away.
