test(client): add BoundaryWall fog tests and document tile_renderer behavior (#585)

Browse Source 
4 new tests in test_fog_sprint22.gd verify BoundaryWall tiles populate
boundary_positions (not visible_positions), get VIS_FORWARD without
EXP_VISIBLE, stay EXP_UNEXPLORED after leaving LOS, and clear on new
snapshot. Comment in tile_renderer.gd documents implicit rendering path.
