feat: Implement Canvas file export functionality and enhance Markdown export process

- Added support for exporting `.canvas` files by rendering them to images and generating corresponding `.canvas.md` files.
- Updated the export logic to handle both Markdown and Canvas files, including file type checks and notifications.
- Improved resource management by ensuring assets are copied correctly and links are updated in the exported content.
- Refactored settings to change default export paths from 'docs' to 'wiki' for better organization.
- Created detailed implementation notes and flowcharts to document the export processes and core functionalities.
