Workflow improvement — Parallel branch preview in Lantern's workflow builder

An improvement to Lantern’s workflow builder: adding a parallel branch without leaving the flow.

The workflow reads top to bottom on a grid canvas: a trigger, a create spotlight step, a condition on revenue and team size, then add tag. The plus beside the condition offers to make it a double branch with conditions, and a preview card draws the result before anything changes, with the current path on one side and the new condition on the other. The header shows the workflow as disabled, with a toggle to switch it on.
