Build an open-source, GDPR-compliant live chat and customer messaging backend using Node.js, Express, Socket.io, and PostgreSQL.

1. DATA MODEL:
- Customer (id, email, phone, gdpr_consent_given, created_at)
- Agent (id, name, email, role, status: online/offline/busy)
- Conversation (id, customer_id, assigned_agent_id, channel: web/whatsapp, status: open/pending/closed, created_at)
- Message (id, conversation_id, sender_type: customer/agent/bot, body, media_url, timestamp, read_at)

2. CORE LIVE CHAT ENGINE:
- Embeddable vanilla JavaScript chat widget (<script> tag) that initializes a WebSocket connection to the server.
- Real-time bi-directional messaging between the widget and an Agent Admin Dashboard built in React.
- Automatic agent assignment based on round-robin routing among agents marked 'online'.

3. WHATSAPP & EXTERNAL CHANNEL INTEGRATION:
- Express webhook endpoints to receive incoming messages from the WhatsApp Cloud API.
- Normalize incoming WhatsApp payloads into the standard Message schema and broadcast to the Agent Admin Dashboard.

4. GDPR & SECURITY:
- Implement explicit consent checkboxes inside the chat widget before conversation initialization.
- Provide an API endpoint (`DELETE /api/customers/:id/data`) that hard-deletes all associated customer conversations and redacts message logs.
- Enforce JWT authentication on all Agent Admin API endpoints.

5. AI TRIAGE FALLBACK:
- When no agents are available, pass customer messages to OpenAI GPT-4o with system instructions containing store policy context to provide answers.
- Include an 'Escalate to Human' trigger word in the prompt that transfers the session to an agent queue.
