Commit Message

fix: store coeffBits in standardBander to preserve ribbon width precision

backSubstitute() was inferring the ribbon width by checking whether
coeffHi is nil — this correctly distinguishes w=128 from w≤64, but
cannot distinguish w=32 from w=64. Both have coeffHi == nil, so w=32
was silently treated as w=64.

This caused the solution struct to carry an incorrect coeffBits value
(64 instead of 32 for w=32 filters) and allocate 32 extra padding
bytes per filter.

Fix: store coeffBits explicitly in standardBander (set at construction
time) and read it directly in backSubstitute instead of inferring it.
