API Adds @chat-adapter/whatsapp with support for:
- Webhook verification (GET handshake + X-Hub-Signature-256)
- Incoming text, media, reaction, and interactive messages
- Outgoing text messages, reactions, and interactive messages
(buttons/lists)
- Thread ID format: whatsapp:{phoneNumberId}:{userPhoneNumber}
- Cache-based message fetching (same pattern as Telegram adapter)
- Error mapping to adapter-specific error types Limitations: edit/delete throw NotImplementedError, typing is a no-op.
