HOL-Light: Prove AArch64 poly_use_hint #486

Summary

Port ML-DSA poly_use_hint HOL Light proofs from s2n-bignum for AArch64
- mldsa_poly_use_hint_32: GAMMA2=(Q-1)/32, for l=5,7 (s2n-bignum PR: ML-DSA Aarch64 HOL-Light proof poly_use_hint_32 awslabs/s2n-bignum#372)
- mldsa_poly_use_hint_88: GAMMA2=(Q-1)/88, for l=4 (s2n-bignum PR: ML-DSA Aarch64 HOL-Light proof poly_use_hint_88 awslabs/s2n-bignum#375)
Includes correctness proofs, subroutine forms, and constant-time/memory safety proofs for both
Adds CBMC contracts for the assembly functions
Updates s2n-bignum pin to cba3956c7a20 (adds UMIN instruction support needed for the l=4 proof)

Thanks @jakemas. Please add the CBMC proofs.

Thank you, added the harness as a single file with split functionality on GAMMA2

This does not meet the bar of a functional correctness proof -- it merely provides bounds for the output?

Thank you @jakemas for working on this!

The specification seems far too weak to claim functional correctness? We seem to only say something about the bounds of the output.

Port the ML-DSA poly_use_hint HOL Light proofs from s2n-bignum to mldsa-native for AArch64, covering both GAMMA2=(Q-1)/32 (l=5,7) and GAMMA2=(Q-1)/88 (l=4) parameter sets. Each proof includes correctness, subroutine form, and constant-time with memory safety. Adds CBMC contracts for the assembly functions. The correctness proof now establishes full functional equivalence with the FIPS 204 UseHint specification (mldsa_use_hint_32_spec), not just output bounds. Includes Barrett reduction equivalence proof and shared infrastructure lemmas in common/mldsa_specs.ml. Resolves: #486 Ported from s2n-bignum PRs #372 and #375.
