Test deployment to Hetzner VPS

[TomGranot]

Goal

Verify GroupGuard deploys and runs correctly on Hetzner Cloud (~$4/mo option).

Steps

• Create a CX22 server (2 vCPU, 4 GB RAM, Docker CE app image, Ubuntu 24.04)
• Install Node.js 22 via nvm
• Clone repo, run ./setup.sh
• Run npm run auth (test pairing code flow)
• Start the service with sudo systemctl start groupguard
• Send a test message from WhatsApp and confirm the bot responds
• Verify Docker container agent executes successfully
• Test guard enforcement
• Monitor memory/CPU usage under normal operation

Acceptance Criteria

• Full setup works on a fresh Hetzner CX22
• Bot runs stable with acceptable resource usage
• systemd service manages lifecycle correctly (start, stop, restart, auto-recovery)
