feat(v4.1): incremental update + large assembly + format robustness

- IncrementalUpdateEngine: dirty propagation, topological rebuild, cache hit/miss - InstanceCache: shared LOD mesh for identical parts - LargeAssemblyManager: BVH spatial index, view frustum culling, assembly stats - format_io: auto-detect STEP/IGES, batch import with error recovery - 31 tests: incremental (11), large assembly (12), format IO (8)
