fix: improve duplicate issue number extraction in auto-close script

The extractDuplicateIssueNumber function now handles both #123 format
and full GitHub issue URLs like https://github.com/owner/repo/issues/123.
This fixes the "could not extract duplicate issue number from comment"
errors that were occurring when the script encountered URL-formatted
issue references in duplicate detection comments.
