wip(assembler): M2 round 4 -- WorldAssemblerHybridV2: exact contacts, tagged tiles 1.18-1.27x MC

Browse Source 
The round-3 'field contact error' measured hit-to-anchor distance; V2 contacts are 0 cm and on the zero
isosurface. Tagged-tile cost 5.7-6.7x -> 1.175-1.270x MC; organic 0.998x. Bound, shelf-thickness and route
audits rerun with negative controls; W1/W8/W16 stable; V1 and MarchingCubesV1 unchanged.
