Breaking change: evolution-service no longer directly accesses
conversations and messages tables.
Changes:
- Add internal API endpoints to conversation-service for service-to-service calls
- Create ConversationClient in evolution-service to call conversation-service API
- Remove ConversationORM and MessageORM from evolution-service
- Update evolution.service to use ConversationClient
This follows microservices best practices:
- Each service owns its data
- Services communicate via API, not shared tables
TODO: Apply same pattern to system_experiences (knowledge-service)
