- bookslm.py: PERF402 — list(_cache) au lieu de la boucle d'append
- bookslm_routes.py: SIM102 — combine les conditions imbriquées (via --unsafe-fixes)
- export.py: DTZ005 — datetime.now(tz=timezone.utc) au lieu de naive now()
- watcher.py: SIM102 — combine les conditions imbriquées

Résultat : ruff check backend/ → All checks passed!
Vérifié : pytest full suite reste 492 passed, 5 skipped, 0 failed.
