Summary

Fix rendering of raw less-than characters in problem descriptions.

Some problem descriptions include inline code like <code>k < 0</code>. The raw < can be parsed as the start of an HTML tag, causing the rendered description to drop the < 0 part.

This escapes raw less-than characters before HTML parsing in both the default and CN normalizers.

Verification

Verified default parser renders <code>k < 0</code> as k < 0
Verified CN parser renders <code>k < 0</code> as k < 0
