Pull request overview

This PR adds an offline “visual traceroute” world map to the Traceroute tool, rendering hop geolocations and hop-to-hop direction arrows with pan/zoom support, and exposes an app setting for default expansion of the map panel.

Changes:

• Adds a new TracerouteMapView WPF control that draws an embedded vector world map with hop markers, arrows, and an info panel.
• Updates TracerouteView layout to host the map under the hop grid with an expander + row splitter, including persistence of the default expanded/collapsed state via settings.
• Adds embedded map resources (cities/country outlines), a generation script, and attribution in the resource documentation list.
