feat(graph-view): implement task deletion and dependency management enhancements

- Added onDeleteTask functionality to allow task deletion from both board and graph views.
- Integrated delete options for dependencies in the graph view, enhancing user interaction.
- Updated ancestor context section to clarify the role of parent tasks in task descriptions.
- Improved layout handling in graph view to preserve node positions during updates.

This update enhances task management capabilities and improves user experience in the graph view.
