Commit Message

bander, solver: add uint32 specialization for w=32

Add dedicated width-32 code paths that use []uint32 coefficient storage
and uint32 operations throughout:

- bander: add coeff32 []uint32 field, addW32(), addRangeW32() methods
  with TrailingZeros32 and uint32 XOR/shift in the inner loops.
  16 coefficients per cache line (vs 8 with uint64).
- solver: add backSubst32() using uint32 state registers and direct
  coeff32 array access.
- Update dispatchers (add, addRange, backSubstitute), reset, getSlot,
  and slowadd to handle the new coefficient storage.
- Update TestNewStandardBander to verify coeff32 allocation for w=32.

Addresses review feedback from @DhruvilK7 on PR #40.
