Add chat deletion functionality across conversation implementations
Browse files Browse the repository at this point in the history
- Implemented DeleteChat and DeleteAllChats methods in Mongo, Redis, Weaviate, and Xun conversation handlers to allow users to delete specific chats and all chats associated with their account.
- Updated the Conversation interface in types.go to include the new deletion methods, ensuring consistent API across different storage backends.
- Added unit tests for DeleteChat and DeleteAllChats methods in xun_test.go to verify functionality and ensure proper deletion of chat histories.
- Enhanced error handling in deletion methods to provide robust feedback during chat removal operations.
