Yansong Zhang 7052257c8d fix(api): use lazy workflow persistence for transparent upgrade of old apps ... VirtualWorkflowSynthesizer.ensure_workflow() creates a real draft workflow on first call for a legacy app, persisting it to the database. On subsequent calls, returns the existing draft. This is needed because AdvancedChatAppGenerator's worker thread looks up workflows from the database by ID. Instead of hacking the generator to skip DB lookups, we treat this as a lazy one-time upgrade: the old app gets a real workflow that can also be edited in the workflow editor. Verified: old chat app created on main branch ("What is 2+2?" -> "Four") and old agent-chat app ("Say hello" -> "Hello!") both successfully execute through the Agent V2 engine with AGENT_V2_TRANSPARENT_UPGRADE=true.
