fix: Chat SDK bridge delivery and typing for non-Discord adapters

- Use platformId directly as thread ID in deliver() and setTyping()
  instead of calling encodeThreadId with Discord-shaped args — platformId
  is already in the adapter's encoded format (e.g. "telegram:6037840640")
- Add triggerTyping() in delivery.ts, call from router on message route
- Enable Telegram channel in barrel
- Verified E2E: Telegram message in → agent → typing indicator → response
