* multi:
- Remove shift_polynomial_coeff
- Remove recover_shifted_data
- Remove recover_original_data
- Move `zero_poly_eval_brp ` under sanity check comment as its only used for sanity checking
* chore: remove sanity check -- this was doing a wasteful `compute_root_of_unity` operation
* chore: add previous sanity check as a unit test
* chore: copy values python was taking a reference, so it passes in our regular codepaths but not in isolated test
* chore: add coset_fft test
* Update specs/_features/eip7594/polynomial-commitments-sampling.md
