Expand the output buffer from 4 bytes to 32 bytes and iterate all 32 positions, so values ≥ 2³² are encoded correctly instead of silently dropped. Update tests to assert 32-byte output and add coverage for 2³², 2¹²⁸, and max uint256 roundtrips. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
