Subject: [PATCH] fix: normalize unicode chars in title matching for artifact
 URL lookup

Add normalizeTitle() that handles en-dash/em-dash, smart quotes, and case
differences when matching paper titles to artifact URLs. Fixes 151 papers
(e.g. USENIX Security 2025) where titles differ only by unicode variants
like en-dash (U+2013) vs hyphen (U+002D).
