fix(benchmark): Hardening multi-agent environment and strict score compliance

- Enforce strictly OpenEnv-compliant scores in (0.01, 0.99) across all paths
- Implement smart prompt truncation to fix API errors
- Introduce domain check LRU caching
- Increase dataset size to 41 cases (added 9 new hard tasks)
- Convert to Docker multi-stage build mapped with Gunicorn
- Overhaul Web UI for correct dashboard logging
