Cobblemon Routes

Fixed — route elevation, waystone names, arrival banner

• Routes no longer arrive on the rooftops of cities, and the exaggerated Y jumps are gone. The route frontier carried its starting Y forward instead of following the terrain, so tunnels bored at the wrong height and a mountain-crossing road kept the mountain's elevation all the way into a lower city. The frontier now re-anchors to the actual ground at the end of each segment, so routes descend toward a city instead of landing on its roof. Tunnels also trigger on a smaller climb (rise ≥ 6, was 8) for flatter roads through hills.
• No more nameless waystones. A GenerateWaystoneNameEvent hook gives any blank waystone (our spawn waystone, or any the pack left unnamed) a deterministic city name; real structure/town names (e.g. "Camphrier Town") are kept. Already-placed blank waystones are also named when first activated.
• The "Now entering …" banner always matches the waystone now. It only fires for a REAL (waystone- or structure-confirmed) name, never a predicted placeholder — so it no longer announces a made-up name that differs from the waystone you actually see.

Diagnostics

• Xaero chunk-paint: the client now logs how many cities/routes it received, and logs once when the highlighter actually paints a chunk — to pinpoint, in-game, whether a missing tint is a data or a render problem (registration itself already succeeds).
