**Motivations:** - Export Signet and mining wallet backups to git with only 2 versions kept - Document and add backup/restore scripts for signet and mining wallet **Correctifs:** - Backup-to-git uses SSH URL for passwordless cron; copy timestamped files only; prune to 2 versions; remove *-latest from backup repo **Evolutions:** - data/backup-to-git-cron.sh: daily export to git.4nkweb.com/4nk/backup - save-signet-datadir-backup.sh, restore-signet-from-backup.sh, export-mining-wallet.sh, import-mining-wallet.sh - features/backup-to-git-daily-cron.md, docs/MAINTENANCE.md backup section - .gitignore: data/backup-to-git.log **Pages affectées:** - .gitignore, data/backup-to-git-cron.sh, docs/MAINTENANCE.md, features/backup-to-git-daily-cron.md - save-signet-datadir-backup.sh, restore-signet-from-backup.sh, export-mining-wallet.sh, import-mining-wallet.sh - Plus autres fichiers modifiés ou non suivis déjà présents dans le working tree
