Subject: [PATCH] fix: iterate past rejected middle matches in
 matchDateAtBoundary()

When the first regex match is a rejected middle-of-text date, continue
searching for subsequent matches instead of returning null. This fixes
cases like "The 9/11 Report due 10/12" where 9/11 is rejected but
10/12 at the end should still be parsed.
