Upload GPX files into a folder hierarchy (traversal-safe path resolution against the store root), browse them in a tree panel, and toggle each one's waypoints/tracks on the map. Waypoints render as clickable points showing name, description and time; bare URLs in the description are turned into safe links. GPX layers survive switching between the Online/Offline base map, same as the radar overlay. Adds rexml as an explicit dependency — it moved to a bundled gem in this Ruby version and isn't picked up by Bundler otherwise.
