full API key integration: prefer free keys, fallback to Kaggle

remove ollama/openclaw, full live logs

fix: kaggle sm_75 + pre-built wheel, OpenClaw+Ollama on clean base, no health-check

fix: replace openclaw health-check image with python:3.11-slim, eliminate spurious pauses

fix: move ollama install to start.sh for faster build, prevent Space pause during build

fix: python status server on 8080 so nginx never 502s regardless of openclaw

fix: python json config (no heredoc), fallback http server on 8080

fix: sync_hub clean rewrite, openclaw password key, 7b model, sleep infinity keepalive

fix: sync_hub syntax, openclaw password key, is_private bool, remove double logging, 14b model

clean: full pipeline, no secrets in history
