Scott Idem 576f22216a feat: restic backup of home/ with systemd daily timer
- backup.sh — backs up home/ (persona data, memory, tasks, crons) to a
  local restic repo; auto-generates password on first run, prunes to
  7d/4w/6m retention; excludes sessions/ and session_data/
- install.py — setup_backup_timer() installs cortex-backup.service +
  cortex-backup.timer (daily 03:00, Persistent=true); skips gracefully
  if restic is not installed

Password lives at ~/.config/cortex/restic-password (chmod 600, not in git).
Repo defaults to ~/backups/cortex-home-restic; override via RESTIC_REPOSITORY.

Per-user encrypted backup is a noted future feature.
