gitea.jordbo.se occasionally returns Internal Server Error (HTTP 500)
on the first request after idle, breaking pi-toolkit/pi-extensions
clone during build. Wrap clones in a 5-attempt retry with linear
backoff (5s, 10s, 15s, 20s, 25s = up to ~75s total). Same fix should
be applied to opencode-devbox/Dockerfile.variant.
