When an AgentBot is assigned to a conversation after the first message
has already been received, the bot does not respond because it never
receives any event. The `message_created` event fires before the bot is
assigned, and the bot has no way to know it was assigned.
Chatwoot already dispatches a `CONVERSATION_UPDATED` event when
`assignee_agent_bot_id` changes, but `AgentBotListener` wasn't listening
for it. This fix adds a `conversation_updated` handler so the bot
receives a webhook with the conversation context when assigned.
## How to reproduce
1. Customer sends a message → conversation created, `message_created`
fires
2. System processes the message (adds labels, custom attributes)
3. System assigns an AgentBot to the conversation via API
4. **Before fix:** Bot receives no event and never responds
5. **After fix:** Bot receives `conversation_updated` event with
conversation payload
## What changed
- **`AgentBotListener`**: Added `conversation_updated` handler that
sends the conversation webhook payload to the assigned bot when the
conversation is updated
## How to test
1. Create an AgentBot with an `outgoing_url` pointing to a webhook
inspector (e.g. webhook.site)
2. Send a message to create a conversation
3. Assign the AgentBot to the conversation via API:
```
POST /api/v1/accounts/{id}/conversations/{id}/assignments
{ "assignee_id": <bot_id>, "assignee_type": "AgentBot" }
```
4. Verify the bot receives a `conversation_updated` event at its webhook
