Implémente les trois fonctions de gestion de snapshots SQLite: - make_snapshot: crée un snapshot gzippé cohérent via sqlite3.Connection.backup() - write_snapshot: écrit le snapshot décompressé à destination - verify_integrity: valide l'intégrité d'une base avec PRAGMA integrity_check Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
