feat: Add Chatwoot Agent Bot prototype and FAQ knowledge base

- Created chatwoot-agent-bot/ with Node.js webhook server
- Bot detects intent (greeting, billing, technical, features, account)
- Auto-responds from FAQ knowledge base or escalates to human
- FAQ-KB.md: Living knowledge base that grows with customer questions
- CHATWOOT-SETUP.md: Complete deployment and configuration guide
- Supports Telegram notifications on escalation
- Bot runs on port 3001, ready for Chatwoot webhook integration
