🎯 Connection Selection Feedback Examples

✨ New Features

• Added connection_selection_feedback_figure example demonstrating figure-level SelectionFeedbackPolicy via custom router

🔧 Improvements

• Made installEditPolicy() and uninstallEditPolicy() chainable in Canvas.js, Figure.js, and Line.js
• Added helpful console warning in Line.js when incorrect SelectionFeedbackPolicy type is used
• Improved code quality with ES6 spread operator for config merging

📚 Examples

Both examples show visual feedback for selected connections:
