standalone: VoxelForgeCore library -- the fast generator behind a clean C++20 API, output unchanged
- Standalone/Core: public header VoxelForgeCore.h (no Unreal types), static library target, ResolvedWorldSnapshot (from the schema-v1 JSON), World (compile, generateTile, density/sign, point/segment solid, classifyBox), host-supplied JobScheduler (the core starts no threads), sequenced, idempotent EditTransaction returning affected tiles per LOD. - The viewer, benchmarks, edits and audits run on Core; StreamingWorld stays host code. - Same as round 11: 11 hash rows at W1 and W8, routes 5642/5642, look/passage/far audits pass, bad-shell control fails, six fixed captures byte-identical; cold W8 1.025 s vs 1.041 s reference. - SHARED_CPP_LIBRARY_PLAN.md rewritten for a UBT module compiling the same sources via shims. Open issue before Unreal: Core's implementation still compiles the Compat stand-ins named like Unreal types (TArray, FVector...); inside a UE binary that is an ODR clash. Must be namespaced.
