Ullrich Schäfer 3345ef127e Add bidirectional elevation chart ↔ map interaction ... Three new interactions: 1. Route hover → chart: Invisible interactive polyline (weight 20, opacity 0) detects mouse hover on the route, computes cumulative distance, and highlights the corresponding position on the chart. 2. Chart click → map pan: Clicking the elevation chart pans the map to center on that point along the route. Uses 5px threshold to distinguish from drag. 3. Chart drag-select → map zoom: Dragging a range on the chart shows a blue selection overlay, then zooms the map to fit the route coordinates in that range. "Reset zoom" button appears to restore the full route view. State flow avoids feedback loops: external highlights (from map hover) set the chart crosshair without re-emitting onHover back to the map.
