Pull request overview
This PR updates the DataGrid AI Assistant chat flow to support regenerating failed requests, aborting in-flight requests when the chat closes, and clearing the chat history by clearing the underlying message store.
Changes:
- Add abort handling for AI requests (including a dedicated “request stopped” message) and abort requests when the AI chat popup closes.
- Implement “regenerate” by re-sending the original prompt for an existing AI message and resetting that message back to the pending state.
- Add a
clear()API to the AI chat wrapper to clear the store and reload the chat datasource; update unit/integration tests accordingly.
