Subject: refactor(examples): migrate renderers to return RenderResult and add
 std::io::Write import

Replace r_println!/r_print! macro usage across all example renderers
with
explicit RenderResult construction using std::io::Write, enabling more
flexible output handling and reducing reliance on macro-side effects.
