refactor(bigint): use len check + unsafe_get in mul dispatch

The view-pattern form (`limbs[:len] is [single]`) does not produce
optimal code yet, so go back to the plain `len == 1` comparison, but
fetch the limb with `unsafe_get(0)` to skip the bounds check — `len`
is always >= 1 by the struct invariant.
