* feat(relay): one-cell flag write workflow with dry run, compare-and-swap and read-back
Operate Relay Production Cell Flags writes cells/<cellId>.json for one
cell: it checks the origin answers as that cell with a flag channel,
refuses a stale expected generation, writes with ifGenerationMatch,
stamps the actor and run on the object, and waits up to 15 s for the
cell's runtime status to report the new generation applied. The deploy
Workload Identity condition admits the new workflow.
* fix(relay): flag workflow retries a transient 5xx, shows the plan before the generation check, and names the failure
Runtime-status reads go through the shared one-retry admin helper, and a
failed read-back poll no longer ends the wait early. The plan line is
logged before the generation check, a failure is logged as one JSON line
the job summary carries, and the object and summary name the triggering
actor.
