Stabilize G004 contract integration after worker merges

Constraint: G004 worker integrations introduced unparseable approval-token tests and a conformance path bug that blocked leader verification.\nRejected: waiting for another auto-integration cycle | local leader verification had exact parse and fixture failures to repair safely.\nConfidence: high\nScope-risk: moderate\nDirective: Keep approval-token regression tests in cfg(test) modules or integration tests, never inside type definitions.\nTested: cargo fmt --manifest-path rust/Cargo.toml --all -- --check; cargo check --manifest-path rust/Cargo.toml -p runtime; cargo test --manifest-path rust/Cargo.toml -p runtime approval_token -- --nocapture; cargo test --manifest-path rust/Cargo.toml -p runtime --test g004_conformance -- --nocapture; python3 .github/scripts/check_doc_source_of_truth.py\nNot-tested: full workspace test suite; remaining G004 tasks 1-5 still non-terminal.\n\nCo-authored-by: OmX <omx@oh-my-codex.dev>
