Configures stable constraint naming so autogeneration produces clean diffs. Alembic uses the sync psycopg driver while the runtime app uses asyncpg. Also fixes a .gitignore bug caught during this task: the bare 'models/' rule for the ML weights volume was matching backend/app/models/ (Python package). Anchored all volume rules to repo root (/images/, /import/, /downloads/, /models/, /postgres_data/, /redis_data/). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
