A brand-new "+ New" workflow is created with unsaved=true and kept out
of the hub's scheduled/unscheduled lists while the user is still building
it in the Edit Agent. The first commit (Save) clears the flag and the
workflow appears. Every other create path stays visible immediately.
Generate a title + description from a workflow's steps (one aux call,
reused for step labels) whenever it is still auto_named, so a workflow
built in the Edit Agent names itself on commit instead of staying
"New workflow". A manual rename sets auto_named=False and is never
overwritten. Stream the aux call (non-streaming drops content on some
9router lanes) and fall back to a step-derived title when the model is
unavailable.
