Review: guard is_multiple_of zero divisor, width-pin lcm(0,0), drop divides

- is_multiple_of now guards a zero divisor (`if other.is_zero() { return
  self.is_zero() }`), matching num_integer's primitive impls — a predicate
  shouldn't panic on `% 0`. (FixedUInt has the same latent panic; both-carriers
  follow-up.)
- lcm(0, 0) returns zero widened to the operand width instead of the minimal
  len-0 zero, so it stays at the caller's width.
- Drop the `divides` override: num_integer's default is already
  `self.is_multiple_of(other)` (and deprecated), so the override was redundant.

Tests: zero-divisor is_multiple_of (no panic) and lcm(0,0) width, both
heapless-internal.
