Publishing or deleting a flow now splices that one flow into the running
graph instead of reconnecting every node in the installation, saving a
shared node's source rebuilds the flows using it, and installing modules
rebuilds only the flows holding a node that would not load.
Renaming stays on the full rebuild — it rewrites message references in
every other flow's document — and so does startup, which has no graph to
splice into.
