fix(core+app): Phase B.3 — Setup.StepUpHeight + scenery road exclusion

Browse source 
Four targeted fixes for user-reported movement/visual bugs:

1. Player entity disappearing: GpuWorldState now supports persistent
   entities (MarkPersistent/DrainRescued). The player character survives
   landblock unloads and gets re-injected into the streaming window at
   the current center landblock.

2. Feet sinking into terrain: +0.15 Z bias in PlayerMovementController
   keeps the character model above terrain z-fighting edge cases.

3. Camera after portal teleport: ChaseCamera.Update now called
   immediately after teleport snap so the camera recenters on the new
   position instead of lingering at the pre-teleport location.

4. Scenery on roads: SceneryGenerator now checks road status at the
   final displaced position (not just the origin vertex), catching
   objects that drift from non-road vertices onto road cells.
