Public launch scope completion

Problem

The YAML contract and normalizer have been validated internally but still contain gaps that are unacceptable for a public launch — undefined behavior for malformed input, missing validation for certain field combinations, and no documented rollback path if a user upgrades and encounters breaking changes. Shipping the core runtime publicly without production-safe compile/normalize behavior and clear rollback guidance risks damaging credibility with early external adopters who expect stability from a launched product.
