fix(merge): VerifyOutcome mock in TestEarlyAckOrdering (lv←main sync)

Same drift as prior sync: my aws-samples#616 early-ACK test mocked verify_build/verify_lint
with a bare bool, but the fork's resolved source returns VerifyOutcome
(build_outcome.passed) → AttributeError. Fixed both mocks to VerifyOutcome(passed=True).
Gates: cdk 173 suites/3416 tests + synth + eslint; agent 1412 tests + ruff + ty (no hang).
