Phase 3 scaffold: chat engine (WebSocket, FCM, pricing, timer, extension, history)
- Backend: WebSocket plugin, chat/pricing/timer/extension/closure/notification services - Client app: ChatBloc, pricing dialog, chat screen with message status, extension/goodbye flow, history - Mitra app: MitraChatBloc, ExtensionBloc, chat screen, extension accept/reject, history - Control center: free trial, extension timeout, early end config toggles - DB migration: chat_messages, session_closures, session_extensions, customer_transactions tables Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
