Improve connector behavior to provide more flexibility and editing efficiency.

Requested improvements:

Allow users to reposition connector text (titles, tags, descriptions) along the line — top, bottom, left, right, or centered — to maintain visual clarity and avoid overlap.

Enable users to drag a connector’s endpoint to a different step without needing to delete and recreate the connection.

These enhancements would significantly improve workflow refinement, especially when reorganizing complex diagrams or iterating on process flows.
