tone: remove remaining overconfident language
- 'all pass'/'all passing' removed from HONEST_REVIEW, LIMITATIONS, VALIDATION, ACCURACY, RELEASE_NOTES, CHANGELOG, benchmark report, paper - 'Production-ready' → 'Validated for architecture-stage engineering' in HONEST_REVIEW, RELEASE_NOTES, CHANGELOG - 'shows this assumption is wrong' → 'suggests' in CASE_STUDY.md - Production/Stable qualified with scope in RELEASE_NOTES and report - .gitignore: exclude stale root app.py (moved to aethermor/app/)
