* feat(gateway): add DingTalk platform adapter

Add DingTalk as a messaging platform using the dingtalk-stream SDK
for real-time message reception via Stream Mode (no webhook needed).
Replies are sent via session webhook using markdown format.

Features:
- Stream Mode connection (long-lived WebSocket, no public URL needed)
- Text and rich text message support
- DM and group chat support
- Message deduplication with 5-minute window
- Auto-reconnection with exponential backoff
- Session webhook caching for reply routing

Configuration:
  export DINGTALK_CLIENT_ID=your-app-key
  export DINGTALK_CLIENT_SECRET=your-app-secret

  # or in config.yaml:
  platforms:
    dingtalk:
      enabled: true
      extra:
        client_id: your-app-key
        client_secret: your-app-secret
