Description:
* SECURITY UPDATE: incorrect regex match in Aho-Corasick prescan (GH#22892) - debian/patches/fixes/CVE-2026-19487.patch: reset the stale failed flag after a successful trie transition in the AHOCORASICK arm of S_find_byclass() in regexec.c, so the prescan is no longer aborted on a worse or non-matching alternative; adds the upstream regression vectors to t/re/re_tests - CVE-2026-19487
