- forward the new simd and jet backend options into HessianConfig /
HVPConfig (jet selects the symmetric Jet representation for Hessians;
HVPs stay chunked HyperDuals)
- HyperDual gained a simd backend type parameter; use the scalar
default HyperDual{1, 1, T, false} for cache translation
- preserve simd/jet when threshold_batchsize rebuilds the backend
- bump HyperHessians compat to 0.3 and test the new option combinations

Maybe requires SciML/ADTypes.jl#176 to merge + tag first?
