Summary
Fix empty coefficient handling in polynomial multiplication.
When either operand has no coefficients, the result length calculation can underflow before allocation:
This returns an empty polynomial early for both owned and borrowed multiplication in the two current polynomial implementations.
Fixes #2639.
