git native issue tracking

Haven’t tried this out, but I was looking for a good way to “take my issues with me me” that would also be friendly to agents. it works by adding refs/issues/* and then using commits as issue events, and trailers for metadata. One nice aspect would be that the working tree you’re in doesn’t get a lot of noise. I think the problem would be that the size of the repo could get really big and take a while to clone if you’re using it a lot.
