feat: CI/CD pour packages .deb et .rpm + tests d'installation

Nouveaux workflows GitHub Actions:
- .github/workflows/build-deb.yml : Build et release DEB sur Ubuntu
- .github/workflows/build-rpm.yml : Build et release RPM sur Fedora
- Déclenchement sur tags v*, push main/master, workflow_dispatch
- Upload des artifacts et création automatique de release

Système de build de packages:
- packaging/build-deb.sh : Script de build .deb avec sanitization version
- packaging/build-rpm.sh : Script de build .rpm (via Docker)
- packaging/Dockerfile.deb : Container Ubuntu 22.04 pour build DEB
- packaging/Dockerfile.rpm : Container Go 1.24 + rpm pour build RPM

Fichiers de configuration systemd:
- packaging/systemd/ja4sentinel.service : Unit avec security hardening
  * NoNewPrivileges, ProtectSystem, ProtectHome
  * CAP_NET_RAW, CAP_NET_ADMIN pour packet capture
- packaging/systemd/config.yml : Configuration par défaut

Scripts mainteneur DEB:
- packaging/deb/postinst : Création user/group, dirs, config
- packaging/deb/prerm : Stop service avant upgrade/remove
- packaging/deb/postrm : Cleanup complet en purge

Spec file RPM:
- packaging/rpm/ja4sentinel.spec : Spec complet avec dependencies
  * Requires: systemd, libpcap
  * %pre/%post/%preun/%postun scripts

Tests d'installation dans containers:
- packaging/test/test-deb.sh : Build + test Docker Ubuntu
- packaging/test/test-rpm.sh : Build + test Docker Fedora
- packaging/test/test-install-deb.sh : 11 tests automatisés
- packaging/test/test-install-rpm.sh : 11 tests automatisés
- Dockerfile.deb/rpm : Containers de test dédiés

Makefile:
- package-deb : Build .deb
- package-rpm : Build .rpm via Docker (no-cache)
- package : Build les deux
- test-package-deb : Build + test installation DEB
- test-package-rpm : Build + test installation RPM
- test-package : Test les deux packages

Tests:
- ✅ DEB: 11/11 tests passés (binaire, config, service, user, dirs)
- ✅ RPM: Build réussi (3.3 MB)
- Version sanitization pour git tags (ex: efd4481-dirty → 0.0.0+efd4481-dirty)

+Description: JA4 TLS fingerprinting daemon
+ JA4Sentinel is a Go-based tool for capturing network traffic on Linux servers,
+ extracting client-side TLS handshakes, generating JA4 signatures, enriching
+ with IP/TCP metadata, and logging results to configurable outputs.
+ .
+ Features:
+ - Network packet capture with BPF filters
+ - TLS ClientHello extraction
+ - JA4/JA3 fingerprint generation
+ - IP/TCP metadata enrichment
+ - Multiple output formats (stdout, file, UNIX socket)
+ - Structured JSON logging for systemd/journald

+%description
+JA4Sentinel is a Go-based tool for capturing network traffic on Linux servers,
+extracting client-side TLS handshakes, generating JA4 signatures, enriching
+with IP/TCP metadata, and logging results to configurable outputs.
+
+Features:
+- Network packet capture with BPF filters
+- TLS ClientHello extraction
+- JA4/JA3 fingerprint generation
+- IP/TCP metadata enrichment
+- Multiple output formats (stdout, file, UNIX socket)
+- Structured JSON logging for systemd/journald
