| 13 | * ChatWebhookController - Handles inbound SMS webhooks from providers |
| 14 | * |
| 15 | * This controller receives POST requests from Vonage/Twilio when customers |

| 17 | * opt-out commands, and publishes real-time events. |
| 18 | * |
| 19 | * Webhook Flow (from SDD lines 1036-1072): |
| 20 | * 1. Customer sends SMS to shortcode |
| 21 | * 2. Provider calls POST /api/webhooks/chat-inbound |
| 22 | * 3. Extract phone and message from provider-specific payload |
| 23 | * 4. ChatMatchingService finds store by latest buy |
| 24 | * 5. If STOP command, process opt-out and return |
| 25 | * 6. Find or create thread for customer |
| 26 | * 7. Save inbound message |
| 27 | * 8. If first customer message, unlock freetext |
| 28 | * 9. Publish Ably event to store channel |
| 29 | * 10. Return 200 OK to provider |
