Commit Message

fix(rational): reject zero denominator in div and reciprocal

Dividing by zero or taking the reciprocal of zero previously produced an
invalid 1/0 value via new_unchecked. Both operators now panic with a clear
message, and div_checked/reciprocal_checked raise RationalError for callers
that want to handle the failure. Add regression tests for both cases.
