Current ComfyUI's PromptExecutor.execute_async indexes cache_args["ram"]
and cache_args["ram_inactive"] on every run. Local fallback execution built
its nested executor without cache_args, so every locally executed subgraph
failed with "'NoneType' object is not subscriptable".
Pass zeroed classic-cache args, and restore ComfyUI's module-global RAM
cache release state after the nested run so the host executor keeps its
RAM-pressure eviction.
