  @moduledoc """
  Adds the `outputs` JSONB column to `workflow_jobs` so we can persist
  the key/value map a runner sends via `UpdateTaskRequest.outputs`.

  Subsequent jobs in the same WorkflowRun read these via
  `${{ needs.<upstream_id>.outputs.<key> }}` — populated server-side
  in `build_task/1`'s Task.needs map per the `runner.v1.TaskNeed`
  proto.

  Storage shape: `%{"key" => "value", ...}`. Empty `{}` for jobs that
  don't declare outputs.
