v1.20.6

Client 1.20.6 + server: scan-scoped radar chains (chains only start from a deliberate PokeNav scan), disconnect forgiveness (a crash no longer breaks your streak), login safety repel, radar overlay UX (scanning indicator, odds gradient red->yellow->green->lightblue, Shiny Odds 1/x line), and the fusion base-stat off-by-one fix (~1/3 of fused stats were 1 base point under the displayed BST).
