Resume Run

Resume a paused workflow run from its last completed wave.

Transitions the run from paused back to running and schedules execution to continue from where it left off — no nodes that already completed are re-executed.

Returns 409 if the workspace already has another active run for this workflow, or if the caller is at the concurrent-run limit. In that case the run stays paused and the caller can retry later. Only runs in paused status can be resumed; attempting to resume a running, completed, failed, or cancelled run returns 409.

Requires at least editor role in the workspace; viewers cannot resume runs.
