Fixes #1368 Previously, was duplicated in 4 places with 3 subtly different fallback behaviors: 1. inline-citation.tsx: returned on error 2. markdown-text.tsx: returned on error 3. assistant-message.tsx: returned on error 4. citation.tsx: returned on error Created canonical in that: - Returns - Strips prefix from hostname - Returns on invalid URL (safest contract) Updated all 4 call sites: - inline-citation.tsx: (preserves original fallback) - markdown-text.tsx: (preserves original fallback) - assistant-message.tsx: (drop-in, both return ) - citation.tsx: (drop-in, both return ) Co-authored-by: guangyang1206 <guangyang1206@users.noreply.github.com>
