Enhance Neo API and conversation management by adding support for server-sent events (SSE) in chat handling, improving error messaging with structured responses, and refactoring assistant creation logic. Update conversation settings to utilize a new assistant model and implement context management improvements for better performance. Additionally, streamline the DSL structure and enhance test coverage for chat functionalities.
