feat(evolution): add real-fit dashboard, API, report builder, and docker compose

- real-fit.html: API-driven research dashboard with agent/model heatmap, detail modal with score breakdown and evaluator commentary
- api.py: FastAPI backend serving /api/real-fit-report (dynamic from SQLite), /api/research, /api/evolve-agent/start
- rebuild-report.py: generates real-fit-report.json from SQLite DB for static fallback
- docker-compose.yml: add evolution-api service (Python 3.12, uvicorn) for research endpoints
- index.standalone.html: sync with dashboard data updates
- archive/index.html: standalone dashboard snapshot (263KB)
- .gitignore: exclude *.db, research-jobs.json from tracking
