rmgr repo-onboard is the missing managed_repos write path. 33 of 44 cache-only
repositories onboarded to central (78 -> 111); the other 11 carry written
dispositions rather than guessed classifications.
T04 uncovered why onboarding only worked from a workstation: the hub resolved
its classification allowed-values file from hardcoded developer checkouts, so
every classification write 500'd in the container. T09 delivers that file.
The local cache database must not be discarded yet — 11 records live only there.
