fix(waf): CRS v4 Regeln extrahiert + Control-Flow-Regeln filtern — v1.2.82
- crsRules.ts neu: 331 echte CRS v4.7.0 Regeln aus installierten Dateien (v3-Nummernschema war falsch, v4 hat andere IDs — 949152 war skip-Regel) - spoe.go: Regeln ohne Message nicht als Alert speichern Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
