Implemented get_cube_root_of_unity() for Grumpkin (co-noir/co-builder/src/honk_curve.rs) using λ = (-1 + sqrt(-3)) / 2 in ark_grumpkin::Fq. Added debug assertions to ensure λ ≠ 1 and λ^3 = 1. This removes the panic from the TODO and unblocks ECCVM endomorphism usage where P::CycleGroup::get_cube_root_of_unity() is required.
