Refactor WorkflowEditor and connection suggestion logic; add SlackNode export

- Removed unused connection handling functions from WorkflowEditor to streamline the component.
- Updated connectionSuggestions to improve cycle detection with a new hasCycleWithEdges function.
- Exported SlackNode from the nodes index for enhanced integration with Slack operations.
