v1.9.4 — Divided Highway Fix, Camera Flicker Fix, Cone Zoom Scaling

Fixes

Divided Highway GPS Snapping

Route segment selection now uses bearing as a tiebreaker when candidate segments are within 15m of each other in orthogonal distance. Prevents GPS from snapping to the wrong side of divided highways when accuracy is poor.

Camera Marker Flicker

Native camera markers now use an atomic swap — the new marker collection is added to the renderer before the old one is removed, eliminating the 1-2 frame gap that caused cameras to disappear and reappear.

Camera Cone Zoom Scaling

Camera cones now scale with zoom level using sqrt scaling (2^(zoom-15)*0.5). Cones grow when zooming in and shrink when zooming out, staying proportional to the road without dominating the screen at high zoom or vanishing at low zoom. Pin icons also scale by zoom group (1.0x/0.7x/0.5x).
