Close the G005 verification gaps before checkpoint

Constraint: G005 requires stale-base doctor consistency, green-contract policy integration, hung-test evidence, and a durable verification map before ultragoal checkpointing.\nRejected: Treat worker task status alone as complete | worker-2 lifecycle was stale-failed despite landed recovery evidence, so leader verification and explicit map are required.\nConfidence: medium\nScope-risk: moderate\nDirective: Keep PR/issue reconciliation deferred to G011/G012; do not mutate .omx/ultragoal outside checkpoint commands.\nTested: git diff --check; cargo fmt --manifest-path rust/Cargo.toml --all -- --check; cargo check --manifest-path rust/Cargo.toml -p rusty-claude-cli; cargo test --manifest-path rust/Cargo.toml -p rusty-claude-cli workspace_health_warns_when_stale_base_diverged -- --nocapture; cargo check --manifest-path rust/Cargo.toml -p tools\nNot-tested: full workspace test suite due known unrelated permission/lifecycle failures from worker evidence.\n\nCo-authored-by: OmX <omx@oh-my-codex.dev>
