Injects credentials as request-time stubs so no credential is ever written
into a container or to disk. Gateway and CLI versions move to versions.json
(machine-checkable pins); breaking upgrades are documented in
docs/onecli-upgrades.md as an agent-executable runbook (detect / why / fix /
verify / rollback), and the update flow follows linked docs and diffs the
pins.
BREAKING: requires a gateway upgrade; the doc carries the steps.
