fix: add environment variable exports to startup scripts

- Added MOMENTRY_OUTPUT_DIR, DATABASE_SCHEMA, MOMENTRY_REDIS_PREFIX exports
- Created run-worker-3002.sh for standalone worker
- Created config/ directory with environment-specific files
- Updated AGENTS.md with critical variables section and release checklist

This fixes Python subprocess environment variable inheritance issue
where store_traced_faces.py was using wrong output directory.
