Add .forgejo/workflows/resume-release.yaml: every 10 min (and on dispatch)
find the highest temp/v* branch, check the release-complete ci-step-status
marker (reused verbatim from release.yaml), and re-dispatch release.yaml on
that temp branch if incomplete. No-op when nothing is in flight or the marker
is set. Concurrency-guarded so overlapping ticks don't stampede.

Tune publish-rust so each run does a short burst then exits fast (cron owns
the 10-min cadence): max-attempts-per-crate 20->3 + max-rate-limit-wait-seconds
90. publish-rust-zreg untouched (no rate limit).
