Run ComfyUI workflows from the command line using comine-san (npx). Use when the user has a ComfyUI-exported workflow_api.json and wants to (1) discover generated CLI options via --help, (2) execute against a ComfyUI server via --server, (3) save aggregated results via --output-json, or (4) script runs with --quiet and troubleshoot common failures (missing file, invalid JSON, cannot connect to server).
