- Removed the `history` model and replaced it with a new `message` model to streamline chat message storage and retrieval. - Introduced a `resume` model to enhance the chat's ability to recover from interruptions, capturing essential execution state data. - Updated the `CHAT_STORAGE_DESIGN.md` to reflect these changes, including new fields and relationships for the message and resume models. - Revised related functions and tests to support the new data structures, ensuring improved integrity and performance in chat interactions.
