Mick Grove c0e4910d1f pattern_requirements for rules — Post-regex character-class gating to cut false positives without lookarounds. Authors can now require minimum counts of digits, uppercase, lowercase, and special characters, with an optional custom special-char set.
Why: Hyperscan doesn’t support lookaheads/behinds, so many “must contain X and Y” checks had to be baked into the regex (hurting readability) or were impossible. pattern_requirements applies lightweight, in-memory checks after a match is found, keeping patterns fast and clean.
