Stabilize G011 integrated evidence

Keep the integrated G011 worker outputs buildable and whitespace-clean before final stream verification.

Constraint: worker auto-checkpoints left a test-scope import gap and committed trailing whitespace.

Rejected: waiting for another worker auto-merge | leader verification already identified the narrow repair.

Confidence: high

Scope-risk: narrow

Directive: preserve the ACP unsupported JSON contract and anti-slop template cleanliness when editing G011 artifacts.

Tested: git diff --check; python3 .github/scripts/check_doc_source_of_truth.py; 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 parses_acp_command_surfaces; cargo test --manifest-path rust/Cargo.toml -p rusty-claude-cli acp_status_json_is_truthful_unsupported_contract

Not-tested: full workspace tests pending G011 final gate.
