Recommendations

1. Downloads: Review ~/Downloads (12GB) — likely has old installers, videos, PDFs
2. Ollama models: ollama list and remove unused models
3. ~/models: Check for duplicate/unused model files
4. Library/Caches: Firefox (105MB), GeoServices (32MB), Tailscale (29MB) — clearable
5. Docker: If Docker Desktop installed, docker system prune -a can free GBs
6. Xcode: If installed, derived data can be 10-50GB
7. Consider: External storage for operator archive, old model files
8. Monitor: Set up low-disk alert (cron job that warns at <5GB)
