Add SCHEMA.md documenting the JSONL attack file format with all operation
definitions, field types, and the burn_lp tokenId convention divergence
between AttackRunner (.positionIndex) and FitnessEvaluator (.tokenId).
Add schema-version header comments to all existing attack files and teach
both consumers to skip comment lines starting with //.
