Add app/infra/ package with: - storage/ - repository adapters for runs, run_events, thread_meta - run_events/ - JSONL-based event store with factory - stream_bridge/ - memory and redis adapters for SSE streaming This layer provides the persistence abstractions used by the gateway services, replacing the old deerflow/persistence modules.
