Shadow Clicks

• tracking clickthrough events originating from the shadows

Pull request overview

Updates clickthrough detection to correctly handle events originating within Shadow DOM by using the event’s composed path, with accompanying test updates.

Changes:

• Switch link-detection traversal from parentElement walking to MouseEvent.composedPath() traversal (Shadow DOM aware).
• Limit traversal depth using CLICK_THROUGH_CLOSEST_MAX_LEVELS over the composed path.
• Update and extend unit tests to mock composedPath(), including Shadow DOM and fallback behavior.
