Found by running: the loop was setting LH_APPLIER_MODEL=qwen3-coder:480b
explicitly via env, which clobbered the applier's NEW default of
x-ai/grok-4.1-fast on openrouter. Result: applier kept hitting the
throttled ollama_cloud account and producing zero patches every iter.
Now LOOP_APPLIER_MODEL and LOOP_APPLIER_PROVIDER are optional overrides;
when unset, scrum_applier.ts uses its own defaults.
