feat(simulation): road-graph hub refinement — scaled-cap hubs, co-location collapse, minor-attach edge split, RailHeadFacing (T-1076)

Browse Source 
is_standalone_hq threaded through CityRecord/CityPlacement via corporations LEFT JOIN (both readers); hubs = top-cap by population among non-HQ settlements (HUB_SPACING_DIAG_PX=64, HUB_CAP_MIN=6); exact-name collapse keeping lowest city_id with loud warn; nearest-point-on-polyline snap (SNAP_MAX_PX=8) with Junction edge-split preserving from<to via norm_edge, else A*-spur to nearest hub; FoundingOrientation::RailHeadFacing{bearing_degrees} assigned at degree>=3 junctions (octant bearing toward dominant incident edge), consumed by skeleton_gen railhead_edge() through the D-234b flush-frontage machinery; believability reader now honours baked settlement_class (stale hardcode since T-1075). 11 new targeted tests; existing suites green.
