Complete self-contained grapho CLI with all 8 phases

Phase 5 (Server): - grapho server setup/mount/unmount/ls commands - SSHFS/NFS mount instructions Phase 6 (SQLite): - State database for event tracking - grapho history command - Events logged for sync/backup operations Phase 7 (Export): - grapho export creates tar.zst archive - grapho import restores from archive - Full data portability between machines Phase 8 (Dashboard): - grapho dashboard generates HTML status page - Dark theme, mobile-friendly - Can be served with python http.server Self-contained improvements: - grapho setup now auto-initializes Syncthing - grapho backup init <repo> runs restic init directly - grapho backup runs restic backup directly - grapho backup list shows snapshots directly - All configs saved to ~/.config/grapho/ Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
