Deep-compare two caller-supplied JSON values with deterministic object-key order

Deep-compare two caller-supplied JSON values with deterministic object-key ordering and explicit index-based array semantics. Returns bounded added, removed and changed paths with primitive before/after values when safe; performs no network request, model inference, persistence or mutation. Base mainnet USDC
