 * bin/gstack-upgrade: the deterministic, unattended upgrade every fix line
 * names. Pinned on its machine lines (`gstack-upgrade: current|behind|upgraded`),
 * exit codes (0 ok, 1 behind on --check, 3 refused with nothing changed) and
 * what it refuses: a dirty tracked byte, a diverged local commit, a pinned
 * (detached or off-default) checkout, an unreachable remote. Never stash,
 * never reset: HEAD, file bytes and the reflog are unchanged on refusal.
 * Fixture: a bare remote with commits A (1.0.0) and B (1.0.1), a depth-1
 * file:// clone at A, ./setup and bin/gstack-capy-install stubs that log argv,
 * on the simulated Capy host (test/helpers/capy-host.ts).
