feat: Add live-build hooks

- Add security-hardening.sh for system hardening
- Add firewall-setup.sh for nftables configuration
- Add qr-code-import.sh for WireGuard QR scanning
- Add disable-package-management.sh to secure package tools
- Add install-scripts.sh to install source utilities

These hooks implement core security and functionality requirements.
