fix(autocomplete): strip lastAccepted boundary from exported workflows (#1093)

The hidden __lm_autocomplete_meta_* widget persisted lastAccepted (insertedText/textSnapshot) into exported workflow JSON, leaking old prompt text even after the user deleted it. Patch app.graphToPrompt (shared by workflow export, Export API and queueing) to strip lastAccepted from the serialized result's widgets_values / widgets_values_named / output inputs. Only the exported artifact is touched; live node state, undo snapshots, copy/paste and local saves keep the boundary intact.
