feat: refactor canvas and node components for improved functionality and styling

- Removed unused hooks and optimized edge handling in the canvas component.
- Adjusted positioning of handles in the compare node for better alignment.
- Enhanced prompt node to utilize incoming edges for dynamic prompt generation and improved user feedback.
- Updated text node to synchronize content changes with the React Flow state.
- Improved logging in edge removal to handle idempotent operations gracefully.
