Add assistant match functionality with RAG and store support

- Implemented `processAssistantMatch` method to handle assistant matching requests
- Added support for limit parameter with default and maximum values
- Introduced `forceStore` flag to control matching method (RAG or store)
- Created placeholder methods `assistantMatchRAG` and `assistantMatchStore`
- Enhanced OpenAI message handling to parse error responses
- Updated message type handling to include error messages

This change adds flexible assistant matching capabilities with initial infrastructure for RAG and store-based matching.
