ci(release): make live-ollama e2e cell non-blocking for publish

The release-e2e ollama cell drives a live 7B model on a GPU-less runner and
is too flaky to gate releases - it blocked v0.17.0 and v0.17.2 from shipping
despite the full test suite and deterministic cell passing. Mark it
continue-on-error so publish gates only on deterministic + reliable checks;
it still runs and shows red on a real regression, just can't veto the release.
