Subject: [PATCH] fix(search): prevent missing matches on same line when
 advancing regex

This fixes a correctness regression where setting regex.lastIndex = lineEnd would skip any subsequent matches on the same line if the query appeared multiple times. Now we advance lastIndex correctly to lineEnd to avoid reporting the same line multiple times for duplicate matches on that single line.
