Fix WebSocket crash + heartbeat default 10min + docs refresh

- Wrap Baileys connection.update listeners in try-catch to prevent
  unhandled exceptions from crashing the relay process
- Add WebSocket-level error handlers in session.ts
- Add global unhandledRejection/uncaughtException handlers in index.ts
- Make listener.onClose error-safe with .catch() in auto-reply.ts
- Change default heartbeat from 30min to 10min
- Rewrite claude-config.md with personality, better explain personal
  assistant features, add recommended MCPs section
