feat: version 1.0.0 avec corrections critiques et nommage de packages

Ajout du point d'entrée principal : - cmd/ja4sentinel/main.go : pipeline complet avec gestion des signaux - Intégration des modules (capture, tlsparse, fingerprint, output) - Shutdown propre avec context.Context Corrections du parsing TLS : - Flow key unidirectionnel (client → serveur uniquement) - Timeout de flux configurable via FlowTimeoutSec - Structure ConnectionFlow simplifiée Améliorations de l'API : - Champs TCPMSS et TCPWScale en pointeurs (omitempty correct) - NewLogRecord mis à jour pour les champs optionnels Mise à jour de l'architecture : - architecture.yml : documentation des champs optionnels - Règles de flux unidirectionnel documentées Système de packages : - Version par défaut : 1.0.0 - Nommage cohérent : ja4sentinel_1.0.0_amd64.deb - Scripts build-deb.sh et build-rpm.sh simplifiés - Extraction correcte des checksums Tests : - TestFlowKey mis à jour pour le format unidirectionnel - Tous les tests passent (go test ./...) - go vet clean Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com>
