Accelerate rules-first feedback and integrate native Strongholds

Apply user priority: save/recovery/privacy/custody assurance after all rules. Add quick types/lint, concise failure-preserving reporter, verbose mode, actual empty-execution guard, signal handling and focused verify name selection; compact canonical context/handoffs without mass moves.
