Fix immediate user message display and ensure high DPI in exec environment

- User messages now appear in blue immediately without rerun delay
- Removed style file dependency in exec environment for reliable DPI
- Manual matplotlib configuration ensures 1200 DPI is always applied
- Fixed chat history to avoid message duplication during processing
