Subject: [PATCH] fix: gracefully handle htmlmin parse errors instead of
 crashing build

Malformed HTML (e.g. unescaped quotes in iframe title attributes) caused
html-minifier-terser to throw a fatal parse error, killing the entire
Eleventy build. Now catches the error, logs a warning, and returns the
unminified content so the build completes.
