Subject: [PATCH] Fix Lexecon CLI server startup and enable
 model_governance_pack import

- Add __init__.py to model_governance_pack to make it a proper Python package
- Update pyproject.toml to include model_governance_pack in package distribution
- Fix RiskScoringEngine to handle missing RiskLevel enum gracefully with fallback thresholds
- Resolves AttributeError when starting the Lexecon API server

This enables the full Lexecon CLI functionality including:
- lexecon init (initialize nodes with cryptographic keys)
- lexecon server (start API server)
- lexecon decide (make governance decisions)
- lexecon load-policy (load policy files)
- lexecon verify-ledger (verify ledger integrity)
