Enhance tracking marker navigation in VideoEditor

Browse Source 
This commit improves the navigation logic in the VideoEditor class for jumping to previous and next tracking markers. It ensures that when at the beginning of the tracking frames, the user jumps to the first marker, and when at the end, they jump to the last marker. Debug statements have been updated to reflect these changes, providing clearer insights during navigation. The specification has also been updated to document the new behavior.
