MajoorGenInfoOverride/MajoorSaveImage/MajoorSaveVideo now use
comfy_api.latest.io.ComfyNode (define_schema/execute) exposed via
comfy_entrypoint(), replacing the legacy NODE_CLASS_MAPPINGS dict style.
node_id values are unchanged so existing saved workflows keep resolving
to the same node classes.
Also bumps @comfyorg/comfyui-frontend-types to 1.54.3 (was pinned to
1.47.12) so JS typechecking matches the frontend versions ComfyUI
actually ships.
