Subject: [PATCH] Fix: pass sender lat/lon as origin anchor for hop
 disambiguation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ADVERT packets have GPS coordinates — use them as the forward
pass anchor so the first hop resolves to the nearest candidate
to the sender, not random pick order.
